Hey guy it's not too bad. I'd keep the nearer leg from kicking back like that, it looks like he is scissor kicking. Right now, get up and jump off something, and see what your legs do. On your falling frame, the guy does not look lke he is getting ready to impact the ground, he looks like he is joyfully floating. If he was moving forward and going to land, hed probably keep his feet forward, and maybe together.
If that doesn't look right, then maybe just extend the leg that he didn't jump off of. So basically, he pushes off with his nearer leg, and his other leg bends up towards his chest to shift his weight off the ground. Then he comes down extends the other leg (the one he didn't use to push off the ground) to catch himself. I really want to make an edit and help figure this out, but I'm on a laptop in Mendocino, the little touch pad is no good for pixeling.
Good luck.
