I was quite happy with the old site design when I put it together. I felt I had achieved a certain number of goals and that it was a success. Over time, and with proximity to people who actually know a thing or two about design, I started to notice lots of little (and some big) annoying details that really detracted from the design. Some of them were fundamental problems of the design, others were due to the way I approached the implementation, and the rest were just things I didn't know anything about at the time.
So instead of setting about to fix them one by one I decided to start from scratch, paying attention to the problems that I'd encountered before. And this is what I came up with. Sure, its probably got its own issues, but I think its a far sight better than the old one.
Edit: I've been playing with Photoshop and my photo archive to create a series of rotating banner images. So far I've got 8, but I might add more later on. Here is a view of all the banners.
