I really like these a lot. That Roman style top is awesome. For the two holding the bow: they are lovely. I'd like something red near the horns, if it's possible. The others: Now that I can see the mouth more clearly, I really don't like it. And I now more than ever think that more is needed on the head since the torso is pretty detailed. Are there any red or black gloves that can layer under the gold cuffs?
Also, how does something like acolyte's dark blessing (lacey cross) look? Nevermind--I tried it and it looks like trash. I feel that you need a bit of black on the chest. But it may be okay if you added to the head.
In terms of backgrounds: what are you looking for? I found Persecuted Halfbreed Alyssia, and then you'd add another background behind that, but I'm not sure if that's the sort of thing you want.
