Yellows look good Ian. HA mentioned, but doesn't really bother me. I might mess around with other crops. I like the habitat but wonder if in tighter would look better.
For me, a tighter crop may have branches coming out of the frame from nowhere and become a distraction. Having the main stem is a great asset to the composition. If it were mine, I would leave the crop as is.
I would prefer the head angle more toward the photographer, in this capture.
Very nice!!
