Portrait — Side-by-Side Results
Prompt
"A dim seaside boardwalk at night, lit by scattered string lights and kiosk glow, as a South Asian man in his late 20s with long braids rockets past on a skateboard, turning his head toward the camera mid-push with a wide, adrenaline grin. Harsh on-camera flash freezes sweat beads on his forehead and the texture of his windbreaker over a plain tee; one hand grips a scuffed tote strap across his chest while the other swings low for balance, with blurred neon, railing slats, and streaked wheels exploding into bokeh behind him (85mm portrait feel, shallow depth of field, authentic nightlife grain). Split-screen comparison frame: left labeled “GPT-Image 2” with slightly cleaner skin texture and smoother noise, right labeled “Nano Banana Pro” with punchier flash highlights, grittier grain, and more pronounced motion streaks—both centered tightly on his face and braids."
