Really liking these!
first one really stands out with that great background and spot on sharpness!
Though it looks like whilst the barn owl rather liked posing the other owl got rather bord of you and your camera
to me the lighting on them looks good - and the shade means you didn't have highlight problems from all the whites on the bird. He is closer to his background though, so it shows up more, which might be more what your feeling.
Also there is a slight (now I look closer) reddy look to the bird but that might just be the bird itself and me looking too close
