Very good
Ive seen better, but this is much better than most of the skating crap submitted here. I especially like the animation you do for the board, it looks cool withn it flips and stuff. You need to work on making it smoother, particularly with the skater and maybe work on your drawings of the skater, if you want. Also, work on your drawings of the props and the background. And your blood animation doesn't look too good, it just spews everywhere. But generally, this is pretty good. keep up the good work, I hope to see more from you!
