 The dithering in the ball is just wrong.

That looks very naughty somehow.

yea, but your avatar annoys me so much

Very funny! Ball shading is bad though, use more colors not dithering. Also you have 'light' crossing over the shadows which is weird. You could do more bend and squash with the ball and even fat on the kangaroo. Overall funny and good but you could push it a lttle further if u want.
