Yeah, I think for a gaming engine you will probably be fine. You would need a few more edge loops around the eyes and mouth for Poser. Looking real nice to me. I started modeling a female figure last year, but I didn't pay any attention to topology or poly count. I did most of the modeling in Sculptris, the little brother of ZBrush, and it ended up over 400k polys (all quads) and no edge loops. You have done way better than I did.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
