i think it needs some color considering the age range the site is aimed towards, the layouts working well though, consider adding a gradient in the backgorund to help spice things up, the typography for the "Nintendo DS Forums" is working well,
i really like it the colours work well together, the only thing i dont like is the image of the DS in the header it doesn't really fit in with the rest of the header in my opinion
I think it only needs a little work. Try matching the page to the header. The bright blue border doesnt match anything either. The header image is good, but the name of the site doesnt stand out enough.
That purple is also used for the default visited link colour isnt it? Couldnt that be a little confusing to the eye?
