I really like the colors in this one. The oranges play very well off the blues and greens. Well exposed.
Nice look back pose. In a perfect world, it is nice to have the head parallel to the image sensor in this type of pose, and your bird's head looks just a bit away to my eye.
As much as I like the rock/lichen, I might trim up just a tiny bit, leaving room for tail, and come in a bit from the right to reduce the bulk of the rock a bit.
Welcome, Asghar, well-captured feather detail,nice background and interesting lichen-covered rock; I agree with Randy's suggestions regarding head angle and composition.
