Very nice entry. I think the preview file is hurting the piece since its hard to tell there is 'more' from just looking at it.
Better!
Maybe it's a bit too much now 
, the increase of width is ok, but the increase in height is not so helpful. See edit here; I've also pointed these stray pixels and given a try to the ouch eye thing.
Still got to take care of that circle! ;)
Edit: btw, the preview isn't clear enough that it's a preview.
I think that the ball would be mostly dark, with highlights at the edges if the sun is directly behind it.
I love it! Great colors and textures, impressive efficiency of the few simple elements.
Some improves are possible:
- the ball is far from the perfect circle,
- the robot shadows might be animated too, a little bit smaller when the robots are higher;
- robots might make an eye or head 'ouch' move when hit;
- stray pixels on the right of bg in the last frame.
ok.. im watching this now in 20minutes and nothing is happening, is that ball going to touch the ground?????? jk, nice
I dont think this counts as a PSP mockup. :/
