Gotta go fast! That reminds me a youtube parody of Sonic [link]
Anyways the speed is nice still needs work. The coloring and shading is what I think you need to work. Good but could be better and more efficient. Guessing you want to try and do a 30 minute challenge in the future. Kudos wouldn't mind seeing it. The product is still quite good even working on it at the speed you did when your not us to it.
