^ To me, she's definitely the most beautiful. Cintia is also gorgeous, but Martha just has something else IMO.
I think most redheads in the industry right now seem to fall into one of two categories:
1. Plain faced tomboy-looking girls.
2. Baby-doll Lily Cole lookalikes
There are few redheads nowadays that are actually unique and really sexy. Cintia, Tiah E ( sort of) and Martha are the main three in my opinion, and Martha is my favorite of them all.
