Really good stuff!
Is that a trick of the perspective; or, for the 2-gun girl standing on the Egyptian head, did you intentionally paint her eyes mostly black and then add a reflection to her pupils? Never thought of doing that ...if that is what you did.
Either way, good models; and I really like the flesh tones you achieved on them. I'm still a bit adverse to injecting to much colour into flesh tones beyond shading (etc).
