Ok now that I have had some time to really look at this one and only because this is such an outstanding image in the first place, in my mind anyway, and deserves the very best presentation possible, I am going to point out three things that I see when viewing the image in the largest size on Flickr. One is there appears to be a noticeable speck of what appears to be sensor dust in the upper right corner, likely more if you look really close. The second is that there appears to be some color noise creeping in, in the upper sky, a good dose of color noise filtration would fix that. Lastly there appears to be some chromatic aberration/color fringing in the branches on the left.
Please do not feel that I am hacking on this image just for the giggles, for my part I would be printing this large, like 24x52 large, minimum, maybe larger if the resolution was there in the raw file, this would be a gorgeous sofa image. At these sizes this picky picky stuff would likely become notable and objectionable.
This is one sweet image.
