Dude, this is great! Nice wind-up, nice execution, the closeup on the face as they get up was really expressive and had a lot of fun details all-around.
I think what could've helped the impact seem a lot harder is a lot more exaggeration in the extremes of the poses- namely, the instant the feet make contact when they weren't supposed to between the full impact of the upper body. There's not enough time to make a lot of flailing motions, but the pose (or even the silhouette) could've been in such a way that it's a little more readable that things have gone awry.
Truly observable talent, even in a short test like this. I'm really looking forward to whatever you got cooked up that's more long-form, and if you ever need a voice actor, hit me up! I'd love to help.
