I'd rate this higher if Sonic's legs looked more like legs than a pinwheel. Also, this has the opportunity for humor. Throw some in.

but please add a preloader next time

Thats was cool but the sonicwas a lil bite strage animated also just 8

It's alright, you've worked well on the camera shots, the animation's pretty impressive. My only problem really is the fact you haven't put a pre-loader on it.

good idea and was done well
