That's quite a mouthful Behzad! You did a nice job with the exposure. The angle of light is less than ideal, but you handled it well. I would tone down the whites in the bugs. I'd like to see a bit more eye contact. Lastly, I think the bird looks a little oversharpened. Thanks for posting!
I like the colour and BG of the image, and the species is a treat to see! However, the head angle is not optimum. As Doug suggests, but put another way, the head needs to be turned about 45° so that the bird is looking more toward the photographer, not away.
great colors and BG. It's sad the the prey is so bright at the top, but you made the best out of it. I'd prefer the head of the bird a little more parallel to the sensor. But this is a great shot, despite all this.
