Pet Photography — Side-by-Side Results
Prompt
"Casual phone-camera selfie at a sunny neighborhood park: a 20s woman with shoulder-length wavy brown hair in a cozy oversized hoodie and biker shorts crouches on the grass, looking near the camera with a candid half-smile while holding her small golden retriever puppy close. Eye-level pet portrait vibe with sharp focus on the puppy’s eyes, warm late-afternoon natural light, slight handheld blur in the background (trees, leash, picnic blanket) like an Instagram story clip. Authentic, everyday moment—no glam makeup, just real-life park hangout energy."
