After looking at Glennie's background painting, I am quite motivated to work on this image. I also think I might have gone a little too much, I wonder if you all feel the same. This photo is FF, f/8, 1/250, ISO 800, at 500mm. Processed in LR first with pretty much taking the highlight all the way down -100 and bring up the white level at around +42. Clean up was done on Affinity Photo (PS equivalent) and some more dodging and burning and also HSL masking on the bottom foliage to obtain similar green hue with the top. It's a shame that this was shot through some foliage and thus the tip of the bill is somewhat smudged by OOF foliage, but I was not too bothered.
