You use grab way too much.
Opener was stiff and twitchy, hand spin was ugly as shit. Here's how to do a proper handspin like that, feel free to use the replay parser or edit it.
You had so many opportunities for big booms but instead you went with tiny 1-2 dm hits which can look good and they can look like the biggest pile of shit ever.
All your replays are just you flipping around helplessly humping every part of uke's body within 10 god damn inches, dude make a pattern for your replay, like I tend to get a split or lower body boom, then got for a decap or upper chest boom then do something with the torso remains.
V How a properish handspin so look, again. Use the replay parser and look at what joints I used.
