This seems to be quite rushed. Knowing some of your other works I must say I'm rather disappointed because I expected much more from you. It's not bad, by no means, but it isn't enough to top Banjax's effort. My vote goes to him.
One of my criteria of this unique theme since it was invented to see how " cool" the bio-racer creation is in totally. I think you started on the right foot, or should I say the right wheels design but somehow the upperbody lacked something that would compliment the fantastic wheel design you made. My vote goes to your opponent.
I'm disappointed that it's not custom, and those thick black limbs don't fit the build at all, but the way you used the kanohi disks is impressive. But it's too simple for me, and I think Banjax tried a bit harder.
Sorry man, Banjax outbuilt you this time. My vote goes to him. I really have to ask: since you made it completely custom you could decide either way, so is there any reason why you didn't want his torso to be poseable?
It does look like it was rushed and you may have wanted to wait a bit and have done some future upgrades but never mind then. But I think you will get positive feedback on those wheels, I think you may need some tutorials :D!!!!
