This is very nice Sergey with a good look back and head angle. Like that "little hair do". The tail being oof doesn't bother me and like what you have done with the bg. Good shot of a skittish bird.
Love the COMP, BKGR, perch and especially the look-back HA. You nailed the focus on the bird's head, but I wonder if a strengthened catchlight might make it pop even more. Excellent, Sergey!
Sergey, I like the look back pose, detail and colours. Interesting colour of the eye, and I would maybe blend in the darker area in the BG just infront of the beak.
