This is an angel/demon tatto, almost completely full back. The original design was taken from the original Diablo game manual, and modified by the artist.
This was done by Brent @ Tattoo Connection, Melbourne, Australia.

(apologies for the lens flare. I've taken about 20 photos and can't get the light right to stop reflections)
Some parts of it are AMAZING!! The detail in the chains are other parts are flawless. The wings texture however does not match the rest of the piece and the line work on the sword is awful...
