Nice shots/ I'd like to see more yellow saturation in the color shot and more contrast in the BW brightening up the whites. Doing that would push the background further back. It's competing too much with the flowers.
Thanks for the comment, Alan.
The yellow (and orange and green) leaves have already been pumped up in contrast and saturation and the background darkened. It is winter. Any more, and it would look garish. Also, the point of the shot (and of my interpretation) is the interplay between the background and foreground, rather than suppressing the background at the expense of the foreground. I think, at the moment, I found the right balance. A week or two from now, I might change my mind
