This is quite good image quality, and a nice subject too! Would have prefered a wider shot (for desktop background). Didn't notice the "shaking" until I read your comment. It's good.
Several of my photos are available for purchase in larger format at Shutterpoint, and some are also available in high quality framed prints at http://djholmes.imagekind.com/
Cool the snake is so defined, I think is the word I'm looking for. Definitely I think the shot should be a bit wider for a full desktop background. But it is a awesome shot.
