The grain and over-tight margins work against this image. Did you crop the image or was this the 300 mm version? The pattern of the birds is a bit unruly but coherent.

I think a clean white background would contribute to your simple composition. A bit more open space on the right may also help. I think the birds need space to move.   Posted: 01/08/2018 01:22:47

I think the plain white background would have been more effective in bringing out the birds.   Posted: 01/08/2018 11:56:56

I agree, I would take the background to basically pure white. I would also experiment with various crops from the left. I often see things in my images that I think are important and leave them in, but after the comments of others or just another look, I find the image gets better leaving something out. In this case, the long trail of birds is impressive, but the image might get better cropping down a bit.

I think it is unfortunate that the birds are flying out of the right of the image. If this is not to be a nature exhibition image, I would add some background to that side of the image.   Posted: 01/09/2018 11:56:14

Ahbijeet, the birds need room to fly as other have said and the background has I think to much grain and should be smoother. For me, it might have worked at that focal length by capturing less of the birds and leaving room on the right. The story, I think is great, it just begs for more room for us to see it and imagine how it unfolds.   Posted: 01/09/2018 12:57:06

I've nothing to add, I agree with the others.

I was reading a National Geographic today (Jan 18 issue) and a guy has been taking videos of birds in flight and then combines selected frames into one image. They are fascinating!   Posted: 01/13/2018 16:13:19

Wow! I'm not a birder but I am always fascinated by natural patterns.   Posted: 01/13/2018 18:17:39
