First off.... I would critique this but I honestly have no advice to offer. This is brilliantly executed and the composition is evocative and powerful. Despite being way more detailed than actual WOW game art, it still captures the feel of the art style the game uses and sets a mood of its own at the same time. The only thing I could possibly ask for to make this work one of my absolute favorites would be a touch more attention to the demon. not detail just brighter colors. I actually didn't see it the first time I noticed this art work, I only saw it after I did a double take for a comment.
Second off... please don't tell my girlfriend I fav'd this, she would laugh me out of the house. She teases me constantly about how in love I am with WOW even though I normally don't like MMOs.
