The baffling choice is obviously giving the water that fluffed / smoothed / "silky" look. At first I thought it was a Photoshop effect, but from a comment from the photographer, Chris Gin, it is apparently from using a multi-stop camera. This effect is pretty common in desktop wallpapers, so I guess a lot of people like it, but man I hate it. The 5th wallpaper above, the one of the waterfall, would probably be one of my 5 all-time favorite desktop wallpapers if not not for the effect, but as it is it's probably my least favorite simply because of how awesome it could have been.
