Layout ideas?

I want to do something new and shiny and exciting about my LJ layout. I lack ideas, though. I think I want to keep the header, even though I might change its colors. I am also still very fond of my font, Trebuchet MS, so I want to keep that, too.

Any ideas what I could do differently?

(and no, neery, I am not making the font any bigger! *gg* Well, I might. But only if it fits with the layout!)
