Beautiful sky colour, and the flock is nicely silhouetted. A few of the larger merges are unfortunate, but that's what you get with birds that flock randomly. I would, however, eliminate some of the partial individuals cut out of the frame...especially the very front headless one, the three lower ones, and the clump of 5 at top. This would not reduce the effect of the scene, but give you a "cleaner" finish comp-wise. Well done!
