I thought those were belt buckles.I can't get past the fact that it is from a western set and has bullets in the belt.
I totally agree with that, that's why I think the fisherman is cool, the viking head just fits with the theme. It's hard to explain.I think the thing that impresses me most about your characters is your careful choice of torsos and heads. The heads & torsos you've chosen do an excellent job of conveying that minifig's character!
