I posted my site here for reviews after a major redesign about a month ago, and I've just added some new features that I think make a big difference. I created 7 new header images and added the Random Image Selector plugin to rotate them. I also added more custom sidebar features that appear to work pretty well with a variety of browsers. I'm sure they probably look like crap if someone sets their browser to display larger type sizes. I've still got a handful of validation issues that I'm trying to track down, but that will be a job for tomorrow. Believe it or not, the whole thing is based on this theme.
