Geoff Shupe (http://chromiumash.blogspot.com/) and I decided about 10 months ago to do some concept art for a story idea that we came up with. We haven't put ALL of our time into it, just a few hours here n' there.
I have had a fun time pushing myself in a different direction than I normally go with my art. It is a challenge but I have learned a ton. Most of these sketches (if not all) are rough, but I thought I would throw some of it up on the good ol' blog.
