I'll second that vote on the arial font..ANYTHING but Times would be better...
The over all site layout looks great from a graphics perspective, all though the logo makes it look like you just bought a template and edited it with your own text..You should make the text a bit more flashy, maybe try downloading some unique fonts??
The top area with the empty white cells makes me think links should be there..Why not just make that a solid white bar, or actually add links in that section?
For your site search, the text in the search box shouldn't read google search, but rather 'search this site' (seeing as it searches your site that would be more appropriate). Also, a handy function to have is this:
<input type="text" name="keywords" value="Search Projects" size="27" style="background-color: rgb(247,247,247)" onFocus="this.select()">
See that section that says 'onFocus'? It'll make it so when I click on that search box, it highlights ALL of the text and I can delete it with my new entry (I use it on both the sites in my sig for the search portion, give it a go..). That way I don't have to delete your text of 'Google Search' before I can find what I'm looking for. All about conviences!!
The images on the far right of your sites logo need alt tags, like 'home' and 'search' etc, just so I know where they are going to take me..
<title>0005_red</title>
Your site needs a more suitable title, meta tags, and a meta description so when it gets indexed by a search engine, people will know what your site is about. I'm sure as heck not going to click on a link that says '0005_red' when I'm looking for a website designer.
You may also want to include subpages for each of the sites you've worked on, maybe with a screenshot of the site, a little blurb about what exactly you did.
Also, you may want to check some of those links. I got a few 404 errors when going through them. Dead links say to me that you don't update your site...and probobly won't answer my contact requests.
Hope this helps!
