My first question is this:
http://www.free-college-girls.com/gallery/freesites/2/
Why the open directory? Why no INDEX.HTML page? I am able to wander around your directories, ignoring most of your pages and skipping right to the galleries...
index.html is your best real-estate... use it wisely! :-)
The content is very overused, especially when used as "teen girl" content. I can still find occasional uses for it for body parts and stuff (like butt shots, etc), but attempting to feature the girls directly isn't going to give you much, most surfers have seen them many times before.
Pixmasters has decent content, but you have to keep ahead of the curve on this stuff or you will find yourself getting less and less listings.
