Joyce Chin has been doing a lot of covers late for Dynamite Entertainment, especially in their new Chaos line of comics including Purgatori, Lady Demon and Evil Ernie. Well, on her facebook page she is sharing the artistic process for some of the covers showing her original sketches, pencils, inks and colors while on others she is showing the original drawing and the finished product. It's fascinating to see just how much detail she puts in and how things change along the way.
Here is the cover for Lady Demon #1.
Here is the cover for Purgatori #3 available here.
Here is the cover for Purgatori #4.
Here is the cover for Evil Ernie #3.
