Hey man...
Ok.......here's the dealy:
-The hand rub at the beginning is no longer a hand rub. It looks more like hes wiping something off of his hand, rather than "getting ready to push the big thing". I don't know if you changed it or if I'm just seeing it in a different light...but that needs some tweaking......
-At the 9 second mark, his elbows lock for 1 frame. This snaps his arms a bit and needs to be fixed
-If you go to the last frame, you can see that in his final pose, his elbows are pointing upwards, which looks very awkward....maybe have them sagging down as if he's tired
Otherwise it looks fantastic!
