Blimey! I'm quite surprised that this is a scanline render. you literally mean just that yeah? No Mental Ray or V-ray in sight? I think it's just me... but the wheels looks blurry! You're probably alright though
I was afraid you mite say that, haha. Not your fault then. Still maybe its just me but theirs looks slightly thicker, because it doesn't have that "about-to-bend" look about it. Anyway I still love it.
