Decent.
It's good for a first submission. Heres some stuff to improve on though.
Please read through all of this review.
First of all when they turn it looks like they are flat. Try not to do that. Draw different angles of them. This takes more time but comes out great.
Second of all add some sounds other than the music from that cartoon (I forget what it's called)
Third make a longer movie. I know this is meant to be a short but try make a longer movie next time.
Fourth it looked too tweened. Try to do FbF (Frame by frame) Which is putting each limb on a different layer and animating them one at a time without using tweens. Takes much longer but it makes movements look more realistic when used correctly.
Fifth I like your style of drawing.
Sixth keep making somewhat humorous cartoons. It seems to suit you.
I hope you improve on the next one. Try to follow some of the critisism I have said. It will make your movies so much better.
