Unfortunately the subjects are too small in this shot and also look out of focus or blurred from camera shake. My recommendation would be to get closer or get a longer lens or zoom.
I feel that I have to comment, to explain my low grading here. Distant birds will work, but there need to be more of them. There is no 'structure' to this composition. It also needs more contrast and perhaps colour saturation, but mainly it needs a subject. Sorry!
