The colors are good. It is simplistic, which is always a good quality. Plus, you have it linked to your social networking sites, so it will help to get the word around. It will do it's purpose well, but there are acouple things i saw that you should take a look at. These are not massive overhauls by any means, nor am I the know all end all, but I though I would toss in my two cents.
1. It's always important to have a menu visible upon opening a webpage. The first thing I had to do was to scroll down and look for a navigation menu. That's a no-no.
2. The expansion menu is a good tool, but only if you use the right images. For instance, before the menu expansion the photos don't really give any indication about their associated gallery. You don't really get an indication of what each gallery contains until you hover over the menu. It probably doesn't seem like a big deal, and it might even seem somewhat cool, but you never want to keep your visitors guessing when it comes to navigation. I'm not saying toss out the expansion menu, but I am saying you should use some different photos for the expansion menu. Right now, if you look at your site the expansion menu (before expansion) looks like four random fragments of different photos. Those photos (before expansion) should give some definition of the associated gallery. If the left side of the photo is visible before expansion, then use photos that are weighted to the left. I hope that makes sense. In other words use a photo that will show the subject of the associated galleries even before a visitor hovers over the menu.
Also, If someone views your site with an older browser, the expansion menu probably won't work. What happens then? If the photos don't have a word on them, plus the photos don't give a good indication regarding the contents of the associated gallery, plus the menu won't expand, then your expansion menu becomes a liability.
3. On your contact tab you write, "it (photography) is not my job..." In my opinion, this makes it sound like you are not a professional, and you don't make money from photography. Which is fine if that's what you are going for, but if you want people to contact you, I would also assume that you would want some of them to pay you.
4. You might want to change the name of your "Beauty Portfolio." It might sound synical, but I automatically wondered if there were any beautiful women in the female portraits gallery. Modeling Portfolio or Studio Portfolio would work, but something that doesn't detract from the other ladies on the site.
