Hey Perfecto,
Just took a quick look at your site, I like the look, very professional and I like the black backdrop, but like Simmo said watch what colors you add to it. Personally I like blue with black (Towers site). I would move some of that text down further cause you don’t want to bore people as soon as they land on your site. Content is great but not all at once, sometimes people just need to know that they can get the content on your site with links and sub menus, it doesn’t have to be in their face. Besides that it looks awesome and you should be proud of it.
