The colour scheme and the side menu looks very nice. I think you should atleast change the logo and the login/logout buttons. And maybe icons too, but they look quite ok with your colour scheme.
Why have you got a HR at the bottom? It doesn't suit your colour scheme, and spoils the look of the site.
OMG, you got an Agony Aunt too? Hehe... I like them, they are actually kinda funny.
By the way, I think I have a set of icons somewhere which matches exactly to your colour-scheme, I will try to find it and send it to you over MSN.
