Reminds me of the video Sad Scyther, except not as funny. The drawing is good though. You did an amazing job on the hands, but there are a few things off about the second panel. The body shows no swinging motion of any kind when attempting that sort of high five and the other arm is missing entirely. Had it been a five of the "up high" variety, then the severed hand would have been higher up or, at least, not perfectly aligned with the arm like that, and while I thought the force of the slice might have pushed the arm down, that cut looks quick and clean. The arm would more likely have still been in the air after the strike. I'm clearly thinking too much about this. Your art is improving and this is proof of that. That's all that matters, isn't it?
