Thanks to all who posted a critique and to Arthur and Mike for their time in posting their versions. This is what I ended up with, and it printed nicely.
I think that I missed the original image Mark but the repost is outstanding in all senses, gob procesing job, excelent composition, good technique. Way to go :-)
I didn't see the original post, but this image is stunning with the layers of color in the background, the soft wings in motion and the sharp heads. All the birds are nicely separated. Good job.
