Here's the process that I took to make my Rotting Zombie Illustration for Mystic Warlords of Ka'a [link]

I forgot to take most of my .psd files for iterations and just took the final .psd files. However, this is one of the few that I actually have to show my process. On a side note I almost never actually do a painting in grayscale. Since May 2011 I almost exculusively paint in color. It seems to speed up my process and I think the colors look better in the finals. Well, hope you enjoy!
