I like the overall architecture, the shape, of the animation, but there's something about the way that the feet slide around on the horizontal axis that really seems to make the overall actions a little bit to floaty. The feet need to be grounded and anchored to the place where they're standing in order to give the whole action a greater sense of authority and kinesis.

In particular, the punch animation has the back leg sliding backwards which really robs it of a feeling of solid connection. The front leg lifting and supporting for the thrust works, the back leg losing traction does not. The grab and throw feels like both arms need to be involved or the character needs to get closer to the target before the actual throw behavior begins.

The aim and fire animations are nicely grounded and sell the feeling that there is some effort going on. Less so in the guy's case because he seems to be half floating during most of that cycle; you might want to think about just committing to going completely off the ground and pointing his ankles downward during the whole thing to sell that idea.

Otherwise, really good.
