I'm fairly new to WordPress and I've been using it for over a month now and I decided to design my own theme for it. Previously, I started using Semiologic's 3-column theme and it was great for awhile. So I decided to read alot of sites on designing a WP theme and after days of trial and errors, it's finally working and it validates. Anyway, check out my site at http://www.photolulu.com and if you have any pointers or suggestions you'd like to share, feel free to comment.
