Put some shading on Thoth's linens. I have one darker round of shadow color I'm going to put in for the deepest shadows; I tried it out just on the upper edge of the back of his skirt. The it'll be on to highlights, and a whole lot of cleanup and smoothing. Well, maybe not that much smoothing, considering the transitions on his skin are not that smooth.
Oh, also did his beard except for the bead at the bottom, and put a smidge of highlight on his eyebrows to help them show up more.
