It looks very 'corporate', which is I'm guessing what you were aiming for based on the type of game. Still though, it looks quite boring to me... I'm not against the concept of the game, but the design wouldn't compel me to want to play it.
Also, I'd ditch the table based layout and use (or learn to use) CSS. Everything you've done there could be done in CSS, and would be semantically correct (leave the tables for actual tabular data, such as for the Nations statistics) and would probably load a bit quicker, too.
The whole design just leaves me a bit cold; it doesn't feel like it's for a game. I understand it's just an alpha build, but I'll still be honest, I don't really like it. It should still have an element of 'fun' in there, corporate or not.
Hope that didn't seem to harsh,
Good luck
Tom
