Lovely colours here, Marko. BG is lovely and suits the bird. Title explains the posture well and you have achieved good sharpness on the eye. Perch is a little heavy but provides a good base for the image - the lichen and fungus on it add character but I might remove the lump below the vent as it looks a little like a "deposit":)
Hi Marko Agree with Tony and might add on the tech side you might want to increase the ISO. I understand it will introduce some noise but it can be dealt with, motion blur no !! You did do great and made a sharp image at slow shutter speed. btw a little fill flash would also help out with sharpness and lighten the belly part !!! I like it a lot!!!
