When he lands his body is a little to stiff. Maybe try having his pelvis go down more. Also right after he lands, he jerks back which looks off. The bat swinging looks great!

I just recently bought a couple of used kinects and tried the ipisoft trail. Overall it works fairly well. My room is not that big, so I can't move around a lot which is the biggest problem. But it does a pretty good job a tracking your motions. The captured motion does get buggered up often in the arms, though, but it can usually be fixed in ipisoft studio.

I'm also wondering about using the gravel_pit night map from sfmbox.com in my saxxy video. Is OK, or do I need permission?
