They are a lot better than I was expecting in the hand. For me they are just below Alpine and Evolution miniatures standard but I would say the faces on the figures I have are very nice. I think some of the straps and belt buckles could be a little crisper. The bodies are close to Alpines size but for me I think some of the heads and helmet sizes are a bit smaller.
As stand alone figures ( same brand in a group) I think most people will be more than happy,
The good news is I tried a Apine head on one of the bodies and it looked fine but the collar on the figure might need to be thinned on the inside as the Alpine head/neck was a little bit thicker.
The 3D artist has already done figures for Alpine so I guess he knows his stuff

I have the guy with the pipe and a couple of others.
