Some of the best pictures in the showcase were done with a mouse. I don't know how they do it, I find it is hard to make nice sweeping and smooth lines with the mouse because of the position your hand is in to operate it. The control is certainly better with the mouse, but working with one kills my wrist, so I stick with my tablet. This is not bad, and certainly better than anything I could do, but maybe you should look at some of the studies and references Clox posted on Kashas figure study.. they do great anatomy and would be your best source for advice.
