Hi Saeid, I like the low perspective here, and well timed to capture the wing flap. Overall well exposed, well placed in the frame, and I do like the colours of the BG.
Please post your camera settings when you post your images. You have stated your camera and lens, but we also like to see your aperture setting, shutter speed and ISO value. The time of day also helps to pass a better critique.
Great low angle, and I like the wing flap. The BG is rather beautiful. I do think the contrast may bit a bit strong, and there are a couple of black specks in the water that I would remove if mine.
Wonderful light and great low point of view.Love the BG (background).
The wing flap is nice. The birds seems a bit"crunchy" to my eye. Is this a big crop?
