Looks good for starters! One can tell that you put effort into painting several layers.
Somehow the layers look a little "rough" though. I can't tell why. Maybe the colours where too dry when applied? I can imagine them looking a little more smooth if you add a little water to them before painting.
Anyways, nice mini. I look forward to seeing more cowboys. You're assembling an entire posse for LotOW, right?
