Really like the c4ds, they sit perfectly. Not sure if the girl fits well though :S. Looks great though . Well done DraveN!
To me, it seems the way the 3d render is place on the side of her face seems like it's coming out of her ear or something. I'd say move it a bit, try some new placements. Or maybe replace it with something else, because I dont think that the 3d renders really belong in that style of sig. Like, its all smudge, and then its suddenly 3d renders. Thought the 3d renders on the left look hot, im only talking about the ones on the right.
