I have some small "hints". When your fist or foot is on its way to hit uke with a powerful speed, be relaxed in the ankle/wrist. That will make the fist/foot go a long way into ukes joints and blow him up. You also need momentum in in your replays or else it will turn out into a terribly stiff shit replay.
More tips later.
Also, I see Micho is heading to the right direction of madman making. Nice ^^
