well they all had some stiffness in them, but not one of them was all stiff.
yep, the first one is the best. It's a bit stiff before the impact though, and relaxing uke is "unethical".
Counter submission was almost realistic in the end, but nobody gets on their opponent quite like that. also the stiffest of these.
Salto-arabica is also a stiff in the flip, but the main problem is you bashing your head on uke.
Laserleg combo was the second-best. Nice flow, not noticeably stiff before the pose. The last kick would be better as a knee. Also I like the shape of the torso, and if you remove the lumbar joint and head, it goes crazy
Success also has the same messiness problem as Salto-arabian destruction.
