Here is a rather rough progression and a detail. I started with Art Rage and worked back and forth with Photoshop to get the canvas wash satisfactory. In hindsight, I should have done the initial sketch and block-in with the darks (stages 1 and 3) more carefully instead of rushing in with the heavy paint thinking I could just fix it all later. I had to do a lot more correcting of the drawing in the later stages because of that. Overall this was a humbling experience. You can see the image I was working from here: http://muddycolors.blogspot.com/2012/01/art-might-online-art-museum.html
And here are some figure drawings from a week ago. 1 mins, 10mins, and 20 min I think.
