The main thing wrong with the flip that I can see is that from the position he leaps from, it would be impossible to jump that high. Even if the stick pulled down on the other one's head to support himself in midair, leaping six feet in the air backwards off of one leg just looks strange no matter how you show it.
Yeah, I see what you mean, and I was thinking about that while I was making it, but I couldn't think of any logical way to make it more realistic.
Thx, I'll mess with it a bit
EDIT: I just lowered the position of the flip and now it looks a little more like he's grabbing his head and using that to get height, Gimme a second and I'll post it.
