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