I second Squirt's opinions. I like your content but neither tour does much for me.

The second tour is so narrow and you are not utilizing much of the available screen area to showcase your content. The only people who will appreciate the width are those surfers still on 13" monitors. I wouldn't use this tour at all because of the width.

The first tour.... I would use much larger images and feature each model individually. When I look at the tour, I don't really know what I would be getting with a membership. I'd really like to get to know the models... maybe see some sample pics and movies.

I would also stop using graphic text gimmicks such as gradients except for on the the splash graphics. It's makes it too difficult to read. Besides "real" text is a SE friendly. I wouldn't fade the edges of the images either. It looks kind of dated. Crisp, clean rectangular images pop off the screen much more.

Imo, bigger is better except for text... keep that small. I believe that big images and wide pages are more pleasing to surfers nowdays. But I may be completely wrong. I'm certainly no expert and the above advice is merely my own opinion.
