I'm having a weird issue of painting the human form, with a mouse. My humans are awful, unless they are traced. Then, I still can't get the tiny details. And the arms and legs aren't right at all. I know, I need a tablet. But despite that, how do you learn to draw the human form? Mine tend to look almost like a lopsided gingerbread cookie. It'll be a few days before I get a tablet. What can you do, to learn to do this, better, with a mouse?
