Lovely colors and mood. I like how you framed this. This is a minor tweak idea, but you might consider blending in the brighter spots on the bird wings and even out the tones of the horizontal yellow sky/reflection in the BG. In any case, I really like this image..................nice job!
I really like this image, Mitch...if it were mine, I might soften or blur the BG just a bit..or, as Jay suggested, even out the tones in the BG some...it might give a bit more separation between the skimmers and the BG. Nicely done!
