Meh. It's subpar. Way too grabby, stiff, messy, and that last dm was way to slow. There's really no style in it. No power in your hits.
You have no residual momentum after your hits, which, granted, is really hard to do, and I really wouldn't expect it of you, but something like this demands continual momentum.
You didn't use enough of your chest to power your hits. Everything was in the arm/pec, which makes things look stiff. Slow down a little and practice on your set ups. The set up is the most important part of madmen. It's not bad to start off slow and work your way up.
You had a couple grab dms, which I don't like.
It also looks like you didn't use much shift + space, although I can't know that for sure.
There was no pose, which is disappointing.
Overall, 5/10. Work on style, and less grab.
