I don't know if you want crits, but here's mine anyway :
1) The right knee on push off on the jump looks strange. It kind of rotates down.
2) In the jump, his arms might lag behind the body more. Also his body should be back more.
3) His landing looks ungainly. I know it's pretty close to what would actually happen, but he's a superhero and he can land how he likes. The main problem is the watcher is looking at his back for a while. I don't know if you've seen Jeff Lew's tutorials, but the last one covers this very subject.
So, I see his landing as his legsstretching out preceeding his body. That way, he won't come forward as much and go out of frame.
