Anime — Side-by-Side Results
Prompt
"In a cramped fitting-room bathroom, a South Asian guy in his early 20s with straight shoulder-length hair takes a mirror selfie, holding his phone up with one hand while the other hooks a thumb into his waistband, shoulders slightly turned to catch the light. Golden-hour sun pours through a high frosted window behind him, creating warm backlight and soft lens flare along the mirror edges, with a smudged glass surface, a wrinkled receipt on the counter, a refillable water bottle, and a couple of minimalist streetwear hangers reflected in the background. Anime-style cel-shaded illustration with large expressive eyes, vibrant hair highlights, dynamic casual pose, and a tiny on-screen caption sticker in the corner reading “Nano Banana 2 vs Seedream 4.5” like an IG story poll."
