King Rock

This was an illustration, a company I worked for used to pitch an idea to a video game publisher. Quite a few years past since than so I guess its OK for me to post it here. It was supposed to be like an action rpg placed in a world imbued with hard rock and metal motives, an atmosphere somewhat resembling metal album covers.
The publisher rejected the idea, and now several years later there is a game called Brutal legend( Jack Black lending his vocals to the main protagonist) with a similar setting . Show how much the publisher (which I will leave unnamed to spare him everlasting humiliation) knows.
