Pretty work on grey skin. I dont know Hasslefree : they make mini basics but cool (not mercantyle surcharging like nowdays mini of GW). The face is really good sculpted and painted : really nasty.
I'm not an expert, but I think you can improve easily the fur in boots but a brush. Personaly, I work more by lavish : a basic clear color and a lavish with a more dark color. (see my Thrud, for example). It's a very simple method, not good noted on this site, but fast and effective (I'm rather a wargamer than a propainter and I have a lots of mini to paint, so...)
