I was just browsing blood elf artwork for references and I really like this one! The subtlety of the smirk is perfect and the choice of having the spell be the lighting is grand! I also like the subtle touches of the eye glow blurring off from his eye, like he was jsut moving, as well as what looks like a rolled up sleeve, like he means business.
Really nice work, I like the rough brush strokes- they give a nice edge compared to the other sleek, pretty-beyond-sight-blood elves that you see around a lot. Beautiful colours and well done lighting too. The flames are just great, what sort of brush did you use on them?
