A few more points:
1. I would remove the vid on the front page. It looks like it was shot on a 2008 Nokia camera. Its sucks. If I was looking at that I would be put off. It makes you wonder if you shot the content on a camera phone. Its also not sexy.
2. You need to be more clear what the level of the content is. By looking it seems that its only topless.
3. If you do not have the webskills to make a site, or the money to pay someone to make one for you (no shame in admitting your low on cash - nothing worse than a webmaster trying to bull everyone by saying they have many sales when we know different), then wordpress is a simple way to set a paysite up with.
4. You need a tour. You do not really have anything like a tour. No one is going to care about your bio and about pages. These will not sell the site.
5. You need a friends tour too. Show the other models you have shot. No one cares that you have told them you have a friends section. You need to show it by showing pics of each extra model.
6. Ideally have an update section. If you do a post, show it. Add a date too. If people think you update each week then they are more likely to join.
7. Aim to non UK too. If I was in the USA would I join your site? Well look at:
http://www.tarateen.com/tara--about-us.html
Its talks about doing a webcam show at 8am. It would be best to say 8pm gmt or somthing. After all 8pm in the USA is not the same as the UK.
8. You still have right click prevention on. Why???? Do you think a webmaster will steal the site design? Also if I was looking to join the site I would be thinking if I joined, would I be able to save the pics to my pc. And as such may be put off by the right click thing.
9. Also a bit confusing is do members get the webcam free. Or do they have to pay extra. I presume that by you saying members get £10 free then they have to pay extra. I think many sites provide it part of the members fee. This would put me off joining. Though later down the page its says something about getting webcam free. This is confusing.
