Russian Swimmer Nikita Konovalov's Illidan Stormrage tattoo.

This almost makes me want to put work into not being a fat, disgusting shlub.

From the Wiki

Konovalov was addicted to computer games, and because of that around 2006 he was skipping school and training sessions for many months. He has a tattoo covering his chest and arms, which is dedicated to Illidan Stormrage, a personage of Warcraft III: Reign of Chaos.

Illidans tattoo looks different in the CGI movies the in-game model also has a pretty different one.
This is the only artwork where the tattoo looks like his is this one and was made by Blizzards Wang Wei 2005. To be fair, the artwork is the only one that the tattoo looks impressive in.
