Great low angle and clean environment. While it is very sharp and correctly exposed for the whites the image is dark... very dark overall. Suggest trying to find a better balance of exposure between the killdeer and the background - probably only possible in postprocessing.
Sidharth, good low perspective and I like the sharpness. I also like the detail and colours, and will go for your repost in pane #7. I would maybe run some NR on the BG.
