I wouldn't be too hard on this map at all. Yes, it's very basic, but the color scheme is pleasing and there are textures to give it a depth. I would suggest you just follow the above advice and add more features to the map--not too many, though, for they would kill the simplicity of the work.

Good luck; I hope you find the help you need to work on it--or, alternatively, that you keep posting specific questions so we can help you fix it. (Although most of your help will likely come after the holiday vacations are over--traffic has been slow over the past couple weeks.)
