My personal opinion, so it will be subjective okay?
To me, it seems dark. There is no area to "focus" on by the user. Everything (header, body, footer) have the same color.
Also, dark text on a dark background has lower contrast and may/will be harder to read. For a photography related site, a dark background color works because you want the color photos to pop out. (but black/white photos pop out better on a white background) But for a site with a lot more text than photos, it may be hard to read.
You can make your header and footer that dark color, and your content area a lighter color. That way, the eye is drawn to the content area, which is the more important section.
