Sometimes I got the feedback that my site is a bit dark and dramatic. So I took myself a long evening / night and made some minor changes.
First of all I changed the Header and Footer from a dark grey to a bright white. Then I removed all the disturbing and drab backgrounds from the galleries. Moreover is the "Photo Page" changed into "Dim the Lights", which means you can see the photo even bigger now by just clicking on the Thumbnail.
I also change the background image on all the text pages into bright photos which are more adequate for a friendly appearance.
