I've been getting more into art lately, so I figured I'd try a couple of Topaz gym leaders, Froy and Torri. This is my first attempt (they are hand-drawn, I'm terrible at computer art):

I'm going to try to make them better. I'm finding it difficult to draw based on models that already have pretty concrete images. Any suggestions?
(In general, I find that I can draw decent heads and bodies or good legs and feet, but never both. I'm not quite sure why.)
