Hey man I like it a lot
Here are a couple of comments:
1) His motion is a bit stiff in some areas. Probably most notably in his first turn around (ie....after his first "sigh" when he's facing away from us, and then he turns around...the motion is a bit rigid during his first weight-shift onto his left foot)
2) In "gotta keep our composure"....the lip sync on the word "composure" looks a bit off
3) When he bends down to get his baseball bat, his pose could use a moving hold since right now he just freezes down there for a second
Everything else looks great! Really nice work and all of the poses are really strong.
I guess my only comment would be that his emotional change seems unmotivated at the beginning. He goes from sort of thoughtful and reflective to screaming and crazy for what seems like no reason....but personally I think that makes the clip all the more ridiculous and funny!
