I'd suggest to remove the popups on the entrance.
What for do You need them? I think that when a normal surfer comes and sees Your site, most probably it aint the only open window in his browser.
The more popups You got - the more You piss them off I beleive.
And black colour I think is good, gives a naughty feeling to the whole site always.
Also would reccomend to remove the entrance warning page if possible and move all needed warnings to the bottom of the index page.
Same reason as with popups. Imagine a surfer got 20 windows open of which one is Your first warning page with a popup with lots of porn thumbs...
Where would You go first? To a blank black page with no porn or other 19 pages full of it?
Otherwise the design and photos really rock!
