I love contrasty, graphics-like b&w, especially silhouettes, and this is no exception.

I have the opposite response from Cdouthitt: for me, that bird adds visual interest because of the silhouette being sharply different from the others.

I also think having two rows of birds brings a nice balance to the random positions of the birds. Grounding it, if you will.

Can't think of anything I'd change. Fun and eye-catching!

(edit - enlarging the download, I see the birds' spots that amersfoot mentions. You could try increasing contrast to see if that removes, or clone them, or actually you could bring them out more with selective edits. Just depends on what you want from the final image, and whether you will print it - and what size. And now I'm thinking they are all starlings except for the one with tail showing. Do you know if that is the case? Just curious )
