I like the forms/masses in the image, the 3 working the diagonal across the sky.
I do find the top of the left most stump a bit distracting, and blurriness there does look a bit unnatural compared to the DOF in the rest of the image.
It might be possible to sharpen the eyes and facial disc of the owl a bit more, although I know that owls feathers often tend to look a bit soft. You also might be able to bring up the brightness of the owl just a bit.
