Way too short but it was actually good.
The animation was good enough. Background too simple with those buildings, but I liked the clouds. It's well draw too. The little guy reminds me of the Cyanide and Happiness characters.
Those are the points why I'm saving this submission instead of blamming it. But still, it's way too short.
You should take your time, don't rush, make something a little longer and submit for us here to see. It would be very nice to see more stuff from you.
The Kickflip part was little slow compared to the rest of the animation, and maybe that's a effect that you were aiming for, but it doesn't seem to suit so well, at least in my opinion.
So, yeah, you have potential. Keep going.
Experience makes the difference.
Good luck.
