My god, she really does look like she could be, like, Fairuza’s sister. I mean, they’re not identical, but definitely related.
Your model is so sexy I had to add one crit:
In the ponytail pic, her lips look a lot fatter than in the modeled glasses pic. I don’t know if it’s an illusion or if it’s due to how you set the camera up or something, but the fatter lips rock. You should totally play that up a little. Not in a “Lara Croft” way, but enough to separate your model from Fairuza a little more.
And I agree that you should look up the pony tail thing. I know that Hash has elastics you can use to tie hairs together, so the addition shouldn’t be too hard for someone who’s built something so complex already.
Oh, also, I find adding detail to be more difficult as well. Plus, you could take your high-res models, render them from angles, and assemble bump maps that way with photoshop. It’d at least be a good starting point.
(BTW, I have only a passing familiarity with Hash, as I’ve yet to buy it and only get to play with it at a friend’s house, but you seem to really be putting it through its paces.)
