I like this photo, but I encourage you to view it larger. Look at the eye of the bird in this size and at the larger size.
One frustration I have about looking at my photos in Flickr, and most sites that resize images is that I optimize the brightness on a larger view. As such, they are suboptimal and generally appear darker than I would like at the reduced size. If I optimize for viewing at the "normal" Flickr size, they are washed out at larger sizes.
Just a little whine for the evening, but perhaps a suggestion in there as well. Do others experience this? Could Flickr develop an algorithm that boosts brightness of images just bit the images that they are rendering down to a smaller size.
