I think that's a very promising clip. It doesn't have that floating from pose to pose look that most of these things do. It's clear you're aware of the challenge of showing weight and mass.
My favorite moment is when he launches himself up the ladder. Little things like the way his left heel sinks a bit when he puts his weight on that foot are nice touches.
Less certain are the moves he has to do when he is shifting from one foot to another or repositioning a foot. (some of those may be unintentional foot slips. I'm not sure.) Those are hard to do and hard to diagnose. The way he supports himself sometimes with his right arm helps to cover these up a bit.
I think the big pulling up gesture he does around 180+ would have served better to accent "see 'em back". Too late to change that now; that would be a major rework.
Does the right hand really need to be drifting from about 150-175?
I'm not real big on mouth shapes, but when you're doing a "w" word like "When you let..." you can probably make it stronger by doing an "oo" shape to precede the "wh", which is what we tend to do anyway. It gives you more of a place to go from than the resting mouth shape and should make the "wh" have a bit more hit to it.
