I have recently set up a site using Elemental (June 2007).
It's proving quite popular with the target audience and the left Google Ads perform particularly well!
I think you've done quite well utilising that many module positions and still having the site look clean. The Google Ad in the top banner blends very well -- it looks like it actually belong there as part of the banner.
If I were to be nitpicky, the thing I noticed is that the RSS and ATOM feeds in the bottom middle module position look a bit strange as my eyes expect them to be aligned to the same top of the two set of link lists to either side of it. It's noticeably higher up. I'm using Firefox 2. Pretty minor though.
