Style direction:
A handheld urban transit photo-collage style combining realistic crowded metro, bus, tram, or
station snapshots with expressive marker-like cartoon doodles, oversized foreground gestures,
white handwritten diary notes, and saturated comic face overlays.
Keep visible:
- Preserve the core visual identity: A handheld urban transit photo-collage style combining realistic crowded metro, bus, tram, or station snapshots with expressive marker-like cartoon doodles, oversized foreground gestures, white handwritten diary notes, and saturated comic face overlays.
- Use BACKGROUND_ELEMENTS to control secondary scene details, textures, signage, props, and environmental cues.
- Use a realistic candid phone-photo as the base layer.
- The scene should feel like a real public transit or dense city moment: visible doors, rails, signs, floor markings, lights, scuffed surfaces, reflections, crowd density, practical clothing, and imperfect handheld framing.
- Draw playful comic-marker doodles directly on top of the photo.
Avoid:
watermark, username, creator ID, platform logo, app mark, QR code, clean vector poster, fully
illustrated background, polished advertising layout, luxury fashion shoot, empty train, sterile
studio, perfect symmetry, glossy mascot illustration, identifiable celebrity, real public
figure, tiny unreadable text
Do not copy source content, real logos, watermarks, platform UI, QR codes, or exact
reference layouts. Keep the visual system, but change the subject, text, and scene.
