When doing realism, try stay more relaxed, you were very relaxed, but when you were in the air sometimes you didn't move very much that's why I said that and don't rush your movements, you don't have to put all your power into doing spin kicks etc etc.
Also didn't seem like you did any moves except spinning and jumping around. You had the right setup and I thought a few times you were gonna do some kicks in the air but mid through you just stopped the kick and landed. Also use hold and relax a lot more than you normally would, it makes it seem more real.

Hmm, as in don't rush your movements, I'm trying to get speed as quick as I can.

I saw your post and tried recreating 0:44 of this video.

Heaps better. You don't need a lot of speed to get good jumps or spins.

aaaaaaa

um i like the youtube vid but the replays are not really as realistic as there soppost to be and the replays are very short.
but some of them look really good

Yeah, Balance really is one thing that troubles me when I try to stay straight when doing spin kicks.
a tip is try and stay on your feet, for example, of course your gonna use your hands for handstands and things but I mean like after you've done a kick for example, to land on your feet, not land sideways. You probably know this already but it's always good to mention. Proper landing helps with executing the next move.
