Nice work! I will say that controlling the character feels quite sluggish; there's a lot of buildup and momentum for quite a low top speed, so the character doesn't turn quite as fast as I'd like.  The graphics- which are amazing, by the way, very detailed and colorful- are also quite large, making it difficult to see what's around you. This combines with the sluggish controls to create a somewhat frustrating experience. Zooming out the camera and increasing the character's ground speed would make the game more enjoyable, I think. 

Overall, good work! You look like you have great things ahead of you.
