Well it's okay...
But you need to work on your drawing. I can see that you animate very well, but the skater are rather... ugly... Heh sorry. So you only get a 6, in graphics, because of the animation of the board...
I haven't seen other submissions by you, so it's really not fair of me to judge your drawing-skills, but based on this movie i think it could be improved...
Hope you don't get bugged about the low scores, but you didn't really expect that with this one... am i right!?!?!?
But keep it up...
