Updates at the bottom of the thread.
I decided to re-do a digital painting I did in May 2007 (here for the curious), as I think I've improved in technical competence and understanding of anatomy since then.
Obviously, it's still nowhere near finished. I'm going to add colour later; I want to try and get it readable in just greys first. The white-ish irises are temporary; they're just there to remind me where to put the real irises later.
Besides generally finishing and tidying it, what needs work? Someone on another board said the cheekbone ridges need a little revision, so I'll try to fix those next.
