Roy, what a beautiful silhouette! If this were mine, I think I'd clone out the three more blurred birds and take a tiny bit off the bottom. I think that would make the infocus birds really stand out and simplify the image at the same time.
Beautiful colors...don't we all wish the world was as beautiful as this every night?
Roy, I think Jules makes a good suggestion regarding the bottom. I also feel that a silhouette usually looks best when tack sharp or intentionally blurred. I might be tempted to evict the OOF ones. I love the mood and the colors.
Very nice composition, Roy, and great first attempt. Has a very quiet feel to it. Like how each silhouette has a slightly different pose, and the reflected orange light against the dark blue is a nice touch. Good suggestions above to make it an even stronger image.
