Gee, thanks for the custom zoom ins Mike, much appreciated

Very nice ofcourse, and even better close up, but the levels are all over the place

Im guessing you do that on purpose for that soft natural look, with a sight blue background, and it works quite well, but you lose a bit of punch.
This tweak was simply level shift to the start of each histogram curve. Its very subjective of course, cant say its "better".
Come to think of it, the way you handle levels seems to have worked to advantage in this case
