Not too sure why you have a dart board as your logo/header background... seems to have no relevence to anything?
Navigation bar looks cramped due to how narrow the body is. Also as you scroll down there are large amounts of emptiness... not sure what youre doing down there but theres no need for the space I guess
Due to the type of site there isnt too much to review... overall nice, just need to look at the header from a visitors point of view.
As said the dartboard makes no sense at all, asides from that I don't really like the shadows which were used. They don't really serve a function, I think it would be easier to read with them just gone.
