In step two I start to flesh it out. Sometimes I'll draw some more loose, scribbly circles to define smaller pieces like the toes, and to round out where the muscles go, but mostly I concentrate on getting a decent outline. Still drawing VERY lightly, I darkened this a lot when I scanned it, and still doing a lot of erasing. I corrected the angle of the left wing, for example, as I filled it in with more detail.
