You have such high quality photos, some sample pics would help sell the site. Especially where the text says "Free Picture Samples! Free Picture Samples! Free Picture Samples!"
The best piece of advice I can give is to take webmaster suggestions with a grain of salt. Pay attention to your stats & tweak from there. Some of my most amateur looking tours that webmasters would rip apart sell great! And I don't have any models half as sexy as you, babe!
