This ugly customer is Rockface, small time thug and hired muscle. He is a bit slow witted, and despite his appearances, is not that aggressive. He is, however, easily led, and his gullibility gets him into a lot of trouble if he falls in with the wrong crowd.
This min is part of a Dungeons and Dragons collectible miniatures game (I think). I bought it loose at a games convention for 20p, and rebased it and repainted it- not a great paint job, just dry brush and ink wash really. Simple, but I think effective.
