it looks okay. my only comment is you could add delay on the body then the arms so it would look more organic .o ther than that it's a thumbs up :D

i think you have that rating because is so short

You used to work with 32 fps, so you can slow down a little bit.

great :P could be a tad bit slower, but dont see why its only 2 and a bit stars? dont get down hearted, its probably trolls and 12 year olds XD :P

I like the style, but you might want to change it up a bit when you start drawing fast action like this. The apex of the jump till the landing does not look fluid. Perhaps stretch the arm and leg till it looks as though it is one motion. It look like a beautiful natural jump till he reaches the top, then his ping hits 500.
