To be honest, your tour looks more like a movie gallery than a paysite, its a little on the empty side, there isnt any text there to do any pre-selling for you, in essence, the people who are hitting your site are getting some free porn and that is about it.

Take a look at some of the designers portfolios and see how different their sites are to yours, a good place to start is http://www.thumbdesigner.com and http://www.curvology.com
