Animating a stick Man throwing a ball

I did this quick tutorial to learn some more tools in Toom Boom and to understand using arcs for animating characters. I feel I did an ok job, and I learned a couple of new tools. My arcs for the upper body I think are fairly good obviously could be better and with more frames could have a smoother look to it, but the aim was to look at arcs, the legs however don't really have good use of arcs and I think look a bit funny.
