Hi Lorant, what I see right away is the symmetry between the Osprey's wing position, and the top fork of the perch - you couldnt have timed it better. I like the head turn from the take off, and great that we can see the talons. Im fine with your vertical comp, but would like to see a traditional landscape comp too.
I like the way the branch and the osprey seem to erupt from the image. It is interesting that the branch and the wings have a similar color and texture and I appreciate the artistic simplicity of the composition. Osprey sometimes appear awkward but this image portrays a more graceful and elegant side of the raptor.
