He's just looking for some help not to show off the replay so this is the right place for it. That replay's pretty good for a new member ^^
However, you should try to gain more momentum and some speed when making replays.
There are many good ways of gaining speed and momentum. The easiest one is to shoot yourself against Uke. You can do that by falling backwards and lower your shoulders, extending wrists and arms. The moment you reach the ground you raise your shoulders and you shoot your legs up and gets into a position for a decap or split.
Want more help? Feel free to PM me and I'll try my best to help you out
