Professional 2D anime illustration. High detail character design sheet. White background. 16:9 aspect ratio. A cafe racer style bike — modern interpretation. Not vintage. Not retro. The kind of cafe racer that exists today — clean, stylish, effortless. Built for someone who rides the way he moves. BIKE DESIGN: Overall body: matte black and dark charcoal as the base. The golden honey yellow accent showing up in specific places — fuel tank stripe, small detail on the exhaust, subtle rim accent. Not dominant — just enough that it catches warm light the same way SEI does. The bike looks expensive without trying. BIKE DETAILS: — Slightly lower handlebar — relaxed riding position — Rounded fuel tank — classic cafe racer shape but modern finish — Short rear cowl — clean and minimal — Exposed pipe exhaust — one side — simple and warm toned metal — Round headlight with subtle gold ring detail — Tires: medium profile — urban but confident — Small sound wave or music note detail somewhere on the tank — barely visible — SEI's mark — Yellow thread bracelet hanging from one handlebar — like he forgot it there — The overall vibe: the bike looks like it sounds good when it runs BIKE SHEET LAYOUT: Side view. Front 3/4 view. Rear 3/4 view. Detail close-ups: fuel tank stripe, exhaust, sound wave detail, handlebar with bracelet. HELMET DESIGN — SEI: Full face helmet. Modern cafe racer style. Matte black base — thin golden honey stripe running along the top center from front to back — same as the tank stripe. The visor: clear or lightly tinted — you can still see his expression through it. A small sound wave detail on the side barely visible. The helmet looks effortless on him. Obviously. HELMET SHEET LAYOUT: Front view. Side view. 3/4 view. Visor up version — showing the easy smile visible through the open visor. NO RIDER. Bike and helmet only. Clean professional design sheet.
