What he said about the bokeh - I wonder if you have oversharpened the image. This can make bad bokeh become truly terrible. Or maybe you just have a bad copy of your 100-400.
Compositionally, I think it would have helped to take either the whole animal, or just a headshot. This is neither one nor t'other, and it doesn't really work for me.
It was capture sharpened and then sharpened for screen display, both in LR. I used the default "landscape" settings (40 / 0.8 / 50). Sliding the mask up helps a little bit, but not much, as does taking amount down to zero, so I don't think it's sharpening that's the problem.
Can you get a sample of a lens that's bad for bokeh? I thought it was a feature of design rather than implementation. It's pretty sharp.
I take the composition point. I'll try a tighter crop. For some reason I cut his back end off when I took it.
I think he was eating the branch, by the way.
