I like it, it has an effective color scheme that doesn't make my eyeballs want to jump out of my head. I have a couple of suggestions:
1: The text on the top of the page, "A World War Two Community", is a bit small and the light effect is a bit too big. But if you were to make the text bigger it would balance itself out. Kudos on not making the effect animation constant too.
2: I really like the background, but if possible, I would lose the tanks. I really like the look of old maps for backgrounds and accents on sites and it fits with the overall theme of your page too. It reminds me of a menu for a WWII shooter ala' MOH.
3: The image you use behind the menu titles makes the text a little hard to read, but not so much that you have to really strain your eyes.
4: I'd use a serif font to help the WWII feel your page has to really give it that nice aged feel to it. Maybe courier...?
P.S. 14 years old huh? I'd almost lost hope in the future of web design from looking at kids' MySpace pages. You've got a great nose for design, keep up the good work.
