>>3815693The problem is exposure, color contrast, and a lack of subject. The birds are too close of the same color as the ground, so it turns the image into a blur on confusion. The image is too bright, so nothing stands out. The image lacks a clear subject so it's boring to look at.
See how a simple crop and adjusting the contrast makes the image look better? The eye goes right to the 2 birds kissing, setting the stage to examine the rest of the birds. In your OP, you have to hunt for something to latch on to and it instinctively makes me want to ignore what I'm seeing.
