This D&D character is a Storm Warden. The illustration was painted a few years ago and appeared in a book called Primal Power. If you're a D&D fan, you can read more about Storm Wardens in this article: http://www.wizards.com/DnD/Article.aspx?x=dnd/4ex/20091012
I was particularly pleased with this painting, in part because the striking lightning breaks up the shape of the vignette nicely. I also thought the muted (for my palette anyway) colors worked well and I was able to capture the differences in texture between metal, cloth, fur and flesh. That can be a difficult challenge!
