I like the blue in your header image [to me that shade suggests something like electricity]. Maybe you could change the gray to something else, because it makes the site looks a little bland. However, colours appeal differently to different people and ultimately, it's your personal taste that dictates colour usage...
Also, although the blue in your header image is nice, the image itself is rather abstract -- perhaps you could use a image that better represents your site's content/concept?
And it should be "communities"...
I told him the same thing, he yelled at me. (the header image)
