Also, I may be influenced by the feeling I'd like to see all three much bigger (twice height and width) - I have always felt this about your pictures (they are so good I always want to see more of 'em) and wonder whether;
you are working on a smaller pixel size/resolution monitor, or
you don't want to 'give away' such high quality images.
Either are valid reasons.
The small size does make it hard to comment accurately/constructively on the technical side though, I don't feel sufficiently sure of my suppositions to air them. I don't see any consistent halos or artefact's from your new process, just an odd thing in one or two places, but not enough to base an opinion, much less a suggestion, upon.
