I think you looked pretty sharp overall. Your punches had good form, and power looked OK. Your footwork is OK, too. I would maybe recommend working around the bag a bit more, but generally things looked good. Your kicks had some decent power! Good use of both legs, too.
I will disagree with Tek9 about crescents on the move or as attacks. I have been on the receiving end of those from RazorFoot, and they can work just fine.
Thanks for manning up with a vid.
