I wanted to try to make a straight punch.
It is actually really hard for me to get right movements, because when i reverse the rotation of the torso the legs tend to turn instead of the upper boy, wasting the momentum.

However, i am posting a couple of replays:

The first one is ok i suppose, the hit is not that clean, but my tori was drunk and couldn't aim well.

The second one was supposed to be a straight punch, but my center of mass was moved backward and i couldn't reach uke's head, so i turned it into a muay thai move, then i ran after the rolling stone.

Any suggestion would be welcome, and if have made some straight punches taht u'd like to share, feel free too.

Thanks for the comment guys, i tryed to be realistic even after the punch, keeping the feets on the ground and balancing a bit. I will try to punch uke using sambo.mod, i think it should look more natural

Of course i can help you, but i'm not that pro ^^
btw, in the first frames i try to put my tori in a guard position, like a boxe one, adding forces only in the upper body keeping the legs completely relaxed. Then I reverse the rotation and push with the legs, trying to go forward. I really don't think i can explain it better, u can edit the replays to see how the joints are moved
