Ah, I have a few of those older Bret archers, and I see what you mean regarding them being relatively flat in style. However, you seemed to make them look good to me.
I've got one box of the new Imperial archers I picked up a ways back, and I'm contempleting turning them into crossbows based off of a picture I've seen of some renaissance era crossbows. I was oringinally going to try to create some horse archers out of them, yet it looked like it was going to be quite the project with the bodies all being connected to the legs. Just robbed two arms from them for a crossbowman on horseback already, and there are plenty of bits for various uses anyway.
