Yes, this was based very loosely off of someone, but not an actor. The original game character was based on one of the game developers, as was this sculpt. Other than that I just looked at reference of the character from the game.
Sweet! You do such spectacular work; I'm still sulking about them not doing your 1/6 Firefly figures, especially Mal, Zoe, and Jayne.
I don't happen to be a computer gamer - I'm old enough that I was already addicted to people-around-a-table-with-character-sheets-and-dice before computer games were worth a woman's time - so I can't judge this guy's likeness, but as a strong human face with a fighter's squint, he just plain rocks.
