Great work on the lot, no doubt about that. The human male looks so content, just quite quaint with doing nothing other hand reading, his collection of souls gems, tomes and bones really add to his personality. The three servants do make a nice contrast between each other, the gnome with adorable pig tails seems very determined, energetic. Almost looks like the night elf is jealous of the human servant, the lighting just finishes it off.
I've seen this before on the Blizzard Fan Art gallery, did you make this or are you just passing it along?
