Side-by-Side Results
Prompt
"A 22–28-year-old woman with long glossy dark-brown hair in a loose claw-clip, natural glam makeup, wearing an oversized heather-gray hoodie and biker shorts, holds her phone at arm’s length for a front-camera selfie while walking past a sunny corner café window, glancing slightly off-lens like she’s mid-sentence for an Instagram story. Candid motion blur in one hand, iced latte visible, warm golden-hour natural light with soft curated Instagram color grading, casual “day in my life” vibe, approachable and real."
Prompt
"A candid, selfie-style professional headshot of a 25–32-year-old woman with shoulder-length dark brown hair (soft waves), wearing a smart-casual blazer over a plain white tee, holding her phone slightly above eye level and looking near the camera with a relaxed, confident half-smile. She’s standing by a bright café window with a clean, muted light-grey wall behind her (simple uncluttered background), natural daylight as key light with soft shadows, minimal makeup, subtle earrings, authentic “just stepped in for a coffee” vibe like an Instagram story thumbnail. Crisp, realistic smartphone photo look, no editorial posing, no dramatic styling."
Prompt
"A candid Instagram Stories-style shot of a woman in her mid-20s with shoulder-length wavy brown hair, wearing an oversized gray sweatshirt, leaning over a kitchen island and looking near the phone camera while holding a fork mid-bite. In the foreground, a beautifully plated avocado toast with poached egg and chili flakes on a ceramic plate, styled with a linen napkin, gold cutlery, a small bowl of microgreens, and coffee steam drifting in natural window light; shot at a dramatic 45-degree food-blog hero angle on a smartphone. Real, slightly messy home kitchen background with a cutting board and scattered herbs for an everyday influencer “breakfast check-in” vibe."
Prompt
"Top-down flat lay overhead shot on a light wood kitchen table: a 20s woman with shoulder-length wavy brown hair and a cozy oversized grey sweatshirt leans into the frame from the edge, looking up toward the phone camera with a relaxed, just-woke-up expression while her hand reaches for a ceramic mug. A casually styled breakfast scene is neatly arranged—oat milk carton, matcha whisk, small bowl of berries, open journal with messy handwritten to-do list, gold hoops, lip balm, and phone with Instagram Story draft visible—balanced composition on a clean surface. Soft natural window light, slightly imperfect candid vibe like a real UGC morning routine post."
Prompt
"A 20s woman with shoulder-length wavy brown hair in a slightly sweaty black sports bra and high-waisted sage-green leggings takes a gym mirror selfie, holding her phone up with one hand and a half-finished protein shaker in the other, looking near the camera with a relaxed post-workout smile. Real commercial gym locker area with benches and a duffel bag on the floor, a few blurred people in the background, harsh overhead fluorescent lighting mixed with natural window light for an authentic “just finished lifting” vibe. Shot like a casual Instagram story/UGC ad, slightly imperfect framing and natural skin texture."
Prompt

Prompt
"A fantasy art illustration of a 20s woman with wavy dark hair in a casual oversized hoodie, bike shorts, and sneakers, holding her phone at arm’s length for a candid selfie while looking near the camera with a relaxed, approachable expression. She’s in a cozy modern café, but the latte art glows with runes and a tiny dragon coils around the mug, while a cloaked elf barista and floating spellbooks blur in the background; natural window light mixes with subtle magical glow effects. Keep it Instagram-story authentic (slight handheld framing, unposed posture, everyday vibe), detailed enchanted elements and soft dramatic lighting without looking editorial or cinematic."
Prompt
"A 20s woman with shoulder-length wavy brown hair in a casual oversized gray sweatshirt and biker shorts holds a minimalist stainless-steel insulated water bottle close to the phone camera, glancing toward the lens with a relaxed half-smile like a TikTok UGC ad. Shot in a bright kitchen with a clean white countertop and uncluttered background, natural window light, catalog-ready clarity with a “multiple angles” feel (front-facing selfie plus slight tilt showing the bottle’s cap and logo). Casual handheld phone-camera framing, true-to-life colors, no glam retouching, authentic everyday moment."
Prompt
"A candid dating-profile style photo of an influencer (mid-20s, shoulder-length wavy brown hair, minimal makeup) wearing a relaxed white tee and light-wash jeans, holding a phone at arm’s length and looking near the camera with a warm, genuine smile. She’s on a sunny city sidewalk outside a cozy café with a latte in her other hand, soft natural daylight and slight street background blur like a real Instagram story selfie. Flattering slightly-above-eye-level angle, casual unposed posture, authentic “just grabbed coffee” vibe."

Natural phone-camera look with soft ambient neon lighting and a little motion blur like a TikTok story clip."
Prompt
"A 20s woman with shoulder-length wavy brown hair in a cozy oversized hoodie and bike shorts holds her phone at arm’s length for a slightly shaky front-camera selfie, glancing just past the lens mid-sentence like a TikTok “morning coffee run” clip. She’s in a small neighborhood café by a foggy window with a half-finished latte, pastry crumbs, and a tote bag on the table, soft natural window light and casual, lived-in clutter. Render as AAA game/film concept art pre-production: painterly brushstrokes, dramatic yet believable composition, environmental storytelling details, matte-painting quality while still feeling like an authentic influencer story frame."
Prompt
"Candid phone-camera selfie of a 20s influencer character design with a distinctive silhouette: short choppy teal bob with blunt bangs, one eyebrow slit, warm freckles, and a tiny star-shaped nose ring; oversized cropped hoodie layered over a fitted ribbed tank, asymmetrical pleated skirt over bike shorts, chunky sneakers, and a crossbody bag covered in enamel pins. She’s half-turned in a cozy neighborhood café by the window, holding an iced latte mid-sip and looking near the camera like she’s filming an Instagram story, relaxed shoulders and slightly messy “just walked in” vibe. Natural window light, casual handheld framing with a subtle mirror reflection behind her, clean costume details and proportions like a game character concept sheet but still a real-life social post."
Prompt
"A 20s woman with shoulder-length wavy dark hair in a casual oatmeal hoodie and black leggings holds a sleek reusable water bottle and glances toward the phone camera mid-sip, half-smiling like a candid TikTok thumbnail. Shot handheld on a city park bench after a workout with joggers blurred in the background, soft late-afternoon natural light plus subtle commercial-grade fill for a clean brand-campaign look and consistent warm color grade. Authentic UGC vibe: slightly imperfect framing, visible phone reflection in her sunglasses, real-world textures and everyday energy."

Natural window light with a soft ring-light glow from the phone, handheld selfie framing with slight motion blur for authenticity."

She’s sitting at a small window-side café table with an iced latte and a messy tote bag, candid “quick check-in” vibe, a few people softly blurred in the background. Natural morning window light with subtle volumetric rays, subsurface scattering on skin, physically-based materials on the glass cup and knit fabric, slight handheld framing like an Instagram story."

They’re standing on a quiet park path near a gazebo with string lights, soft warm golden-hour sunlight, dreamy bokeh, and a slightly imperfect “Instagram story” framing like they just captured a quick wedding-day moment. Natural lighting, realistic skin texture, subtle motion blur from the handheld phone-camera."
