I like your stuff, man,especially the the sort of traces you do around your arms. But when you do a handwave or wave or any kind, or twiddle your fingers. You might want to slow it down. Don't worry about the fast tempo of the beat, your more angled traces can handle that easily, I always found that when you make the wave too fast, you can ruin a lot of the effect it gives to the viewer. People at my highschool trip out on my handflow because what I do is I make a small sharp jerk where I start, an easy smooth flow which will match however fast the song is, and then a sort of rolling like motion of the joints on the point where I end. I wish I had my camera on me so I could show you.
