Featured Artist: Mark A. Nelson
Nelson had a ton of work published at most of the main publishers in the industry since the mid-80's, plus he's worked for Dungeons & Dragons and Magic. The thing is I don't think I've seen him really active in the mainstream for most of the past decade, and finding his galleries of work has reminded me of just how much of a phenomenal illustrator he is with his designs and intensely detailed linework.
