I'm not sure when this happened? However you will notice that in the footer, the color is washed out in the middle by a circular gradient. That is now missing from the feature area? There is nothing marking it out in the general CSS area.
Before you introduced the admin page for setting background images for different parts of the pages, I had used the following custom code, according to a tutorial by another kaptinlin user for using a full page background images (including removing the shadows and highlights from the different sections)
The feature and footer background color are the same, but the footer has a radial gradient to it that lightens at the center, giving a much nicer tone to the whole footer.
This used to work for the feature too. Perhaps it has to do with using the admin background settings....
