You did well with the exposure and details. I think the owl need some room to look at. I wish I could see more room on the right side of the frame which is the direction the owl is looking at.
I can see your ps skills are rapidly developing. Although this is from a higher viewing angle than the images we captured together, it does create a clean background. The eye is nice, but I think your earlier visit with the catchlight would stand out more. Agree with Maxis about looking out of the frame. Use you improving pp skills on one of your earlier shots and post that. I still think the effort of lying on the ground provides for a rmore ewarding picture.
