I painted up my copies of Baron Blackshield and Murgmo yesterday. They turned out nicely. Here are some pics:

I think Baron Blackshield is the better paint job, but the photo came out a bit blurry, especially from the shoulders up. It's painted according to the character art in the Thornkeep book.
I didn't realize there was character art for Murgmo till after I was done -- I never read past chapter 2 of the Thornkeep book, in hopes of someday playing through those dungeons. So he got painted as a fairly standard goblin.
