Nice behavior shot of one of the bullies of the bird world. I don't see a catch light or its very faint. I learned this tip to improve a catchlight from this forum. Zoom in on the eye and if there is any hint of light -- select it and increase the brightness.
looks very mean!! I like the soft light here as well as the shallow DOF Dave. eye works fine for me as it's indicative of the (overcast??) sky you had?
