Hi Kev. Really like your first image of the heron in the nest. #2 is good but that post might have looked a bit better if was just a little higher than the trees / bushes in the background. Maybe? Sorry but the last shot does nothing much for me – just my opinion. What I would say is, being silhouettes, I think all shots could do with the shadows being darkened a bit more, especially #2. I’d imagine a simple contrast boost or else tweaking the Levels should do it.
