I testing the lighting and material. Need some improve-ment
Rendering with blender cycles and modeling by me
PS:I’m not good at control polygons face(Always has too much polys)
This models has One Hundred Ten Thousand polygons ,I think it is too more。
Sorry for poor english。
The saddle seems a little bit high for me. I’m not sure but the chain seems a little loose. Also, I think you forgot about the rear brake. Anyway, it looks good.
Is the light in the scene the only light source? If yes, that is really cool.
The bike seems very angular - but that might be the intended design - otherwise I’m impressed.
