I'm going to go OT here for a second sorry....
Due to our recent discussion about topaz Detail and adjust, I pulled up your first image for a second to play with Adjust. Upon opening it in photoshop it immediately looks sharper. I realize that is also because it is smaller. I'd noticed similar things in the past and never realized till know what the deal is: images uploaded to FM seem to get enlarged a little. I can do a real life measurement and some quick math based on my screen resolution to confirm this. The image displays at 10" wide in photoshop (18.875"(monitor width) / 1920px (my resolution) * 1024 = 10.06") which it should but at 11.15" using Firefox 3.0.15. Your exif does say the image should be 1024 wide.
Again, sorry for the OT but I figure our perception of image quality is based on seeing it at the correct size so this was not completely inappropriate.
Gorgeous shot all over again.
