You are one '/' away from having
valid HTML on your pages.
The only visual thing I would recommend is to tone down the colors. You can use the same colors if you like them, but perhaps you can use them less liberally.
You might improve search engine placement by remaking your headline images as text (h1's, h2's etc) and adding a unique page title for each page.
Oh, and lose the layout table

Looking good otherwise.
