You have some nice colors and textures here, but there's not enough going on to really pique my interest as an image. I guess it might make a good texture desktop, though.
Several of my photos are available for purchase in larger format at Shutterpoint, and some are available in high quality framed prints at http://djholmes.imagekind.com/
I really like the blue. I find the left a bit bright - otherwise this might make a good, non-distracting desktop for those who like - or sometimes like/need - a desktop which really will be a _back_ground.
