hehe, looks excellent! hope you will finish it before the 22! 
the position on the bike for the character in the center, with his hand on the knee is excellent, that s remember me when i ride a bike on little road… 
just one thing on the bike, i make it with PS, better than my bad english…
this part(in green) is really too low, and the size of your tork is not thick enough. the part of the top need more thick.
dont know if you will have the time to re rendering it, but that s a big error for a motorbike, so that s looking strange.
sorry to not saw it before, but something hurts me, and i doesnt know what… now i know… 
keep it up!
ps: big thanks for the surface, works good. for me i will not have the time to re render the track i think, so will be for next fxwar.
