Absolutely! Come on Jeremy, you know you always need to crop or the picture just isn't finished.
As you know, Russ, my view is that it's not finished until it's properly cropped; and it
may be properly cropped straight out of the camera. If it's a 3:2 ratio photograph.Which this one is, I think: this is framed as I took it.
Anyway, thanks for the suggestions, all. I have fiddled with a square crop and I don't like it: it loses too much of the ice formation.
I have, however, adopted Slobodan's suggestion of darkening and lightening the two rightmost falls, which I think constitutes an improvement.
