The logo and drop-down menu's could use some work in my opinion. The logo looks a bit out of place. I would suggest a non-antialiased (bitmap) font to use for the navbar. For the drop down items, justify them to the left, and not the center. (as it looks awkard otherwise)
Thanks for the comments I'll try altering the menus today, and see how it looks. As for the logo, I'll have to think up a new one before I change it
