Nice subject to draw.
Dynamics study?

Yeah, but also working with dodge. Especially a layer that's entirely used for dodge.
I've noticed some artists have an odd bit dodge-light that you really wouldn't notice lest you was looking at the picture closely; that gives it a much nicer definition. Using dodge instead of white (which is what I usually do) in that area somehow brings it out better.

I even looked myself to see if this happens in real life, and sure enough it does just that if the light source hits it the right way.

Oooh, I didn't intend to have it look that way; but now that you mention it it does. I was working with his paw to fit in the 3 holes on the ball. :O)

Good job again. Ya should add a background if ya have time. ;)

let's just hope he dosen't touch the ground and get a strikeout

Ahh the classics never get old. ;) Great job!

My complements to pose and shading
