Pretty Good
Both the animation and drawings were good, but it was a little repetitive. I would try having the guy do more (different) tricks with the skateboard and add more interesting obstacles for him to jump/grind. I don't know if you want to go the violent route, but you could have it be like one of those race games where it starts with a bunch of stick dudes and some die due to various obstacles along the way until there's only one left. That would make it more interesting. :P Overall you have some talent for animating, keep it up!
