Very nice work. I like how you use the distinguished bottom lip, the way eggplantm does. I don't know why but for some reason that bottom-lip thing is very feminine.
I love one-piece suits myself too because you can do so much more with them than a bikini. Though I would suggest a French cut myself. The low hip cut like this... I'm sorry, reminds me of something my grandmother used to wear.
Still I love the detail you put into it, like the spots on the horn gives it an organic feel, and those black tips in the hair... good work.
