I've just finished Relic's Gallic Veteran Command, my first foray in to the world of Gauls who, it turns out, are a lot of fun to work on. Lots of colors and interesting patterns, especially plaids. These figures have a lot of character sculpted in to them. Jacques for one, over there on the right, seems to have taken up a rather grisly hobby. You have to wonder what his friends and family think of that.
The shield transfer is a decal from Battle Flgas (http://www.wargametransfers.com/gallic--celtic-shields.html) and can be purchased on Relic's website along with the figures. I had not used these before, having experience only with LBM transfers. It didn't take me too long to get used to these though, and I am very pleased with them. They have the excellent benefit of remaining moveable for a little bit after they have been applied, so they can repositioned if you have something misaligned. I like to cut them in half and apply the two parts as separate pieces, then paint up the gap of the the shield spine.
