I am linking because file looks crap on GR. I have the tutorial for how to do this under Video Tutorials. Punch takes a while to show, I have it waiting ten seconds before it moves.
I know. Ten seconds is a long time to wait on a signature, isn't it? I figure I shouldn't have it too fast so I'll put it to ten. Just to give people a chance to focus, lol.
The overall signature is not that great. The punch effect isn't anything special either. Took too long to come out, I had already clicked off it before I noticed it. Make it 3-5 seconds. ~ Astral
The original signature had to be resized for HMF so it's a little messed but the thought was there. The punch is just a basic thing for new people to animating and whatnot.
