Good, constructive comments, Julian. When I came to edit it, I was frustrated that there was so little room, top and bottom, and cursed myself for not allowing for that when shooting. So, I tried a square crop, and it was just too tight, felt uncomfortable. So I did think of abandoning it, but soon found myself playing with tones, and thought these two were presentable.
So, in some ways, the damage had been done at time of shooting, and the rest was a case of, "What can I recover?". It has made me more aware of getting as much as possible right in the frame before pressing the trigger. Time will reveal whether I've learned that particular lesson!
Thanks again, Julian. This discussion has been useful.
