This is probably the 6th time I've redesigned my portfolio website, but I finally made it to the point where it is all database driven, and therefore much more easily updated. I'd appreciate any feedback. Link
It looks nice, simple yet elegant. The code is fairly clean too, but the pages don't validate. On one page when I checked it had 119 errors. Not sure if that's important to you, but wanted to mention it.
Other than that though I'm having a hard time coming up with any suggestions. You did very well incorporating user feedback, which a lot of people miss. The only thing I might like more is being able to view a larger image of the files you show off. The web portfolio is kind of hard to see, though your probably not that worried about showing the details.
Ah! I had forgotten to validate my code... I checked it in Firefox and Safari on Mac, and FireFox and IE 6/7 on Windows and figured that covered 97% of browsers. So it functions, and therefore validity is not too terribly important, but it is something that I would like.
Also, I have the back-end set up to allow the user to get a larger version of the images, or to display a bit of descriptive text with each individual image, but haven't decided the best implementation, and I wanted to get the website live ASAP.
