Design: 3 1/2 out of 5

Even though it's a little too busy for my tastes, you definitely have a nice site. It's headed in the right direction, but I feel you've got a fair amount of work ahead of you where the design is concerned.

• The right box throws the whole site off balance. As there is no separate background to it, the whole site seems shifted to the left. Adding a background color to the side box would effectively fix this problem. Adding a rounded corner on the bottom right of it would also keep it from looking odd when the content reaches further down the page.
• "web & graphic design" is a little too hard to read on my screen in the header.
• Also on the right portion of the page, it looks odd to me to see such crucial information put above the rest of the site's content. It was the last thing I read when I gazed at your site. I recommend aligning it vertically just below the navigation.
• I don't like how those dots run the entire width of the content area. Or it could be that they're just too dark. At any rate, I think you should spend a little time on them. They should also use an <hr /> tag, not a <div>.
• On your contact page, I would advise you to supply your email address. There are ways to hide it from harvesting bots, and I am much more comfortable using an email application than a form.
• I think the cursor change over XHTML and other acronyms is fine.
• "Get a quotation for" on your quote page. Maybe it's a British thing, but I scratched my head.

Code: 2 out of 5
Functionality: 5 out of 5

As mentioned above, your CSS has errors. You've got a few oddities in your XHTML and it's a little messy too. Why not make your XHTML strict? You're almost there! As for functionality, I dislike the tag links, but they're somewhat useful. And it's good to see someone using access keys. Might I suggest letting visitors know about them by adding a note in a title tag?
