I like it.
Thanks for all the suggestions: it's interesting to hear others' views on an image.
I've thought a lot about how best to present this shot. In particular, I've printed copies with and without the reeds at the bottom and gazed at them over the last fortnight. I can't bring myself to like the version without them.
However, I do agree with Hans that they need toning down a bit. In fact, I already had a graduated mask lying over them in LR, which I'd used to drop their exposure a bit, so I've dropped it a bit more and decreased saturation just a little. I've also added a bit of warmth. The result is pretty similar to Hans's version.
Thanks again. It means a lot to an amateur snapper like me when people here say they like one of my images. With this kind of input, I might just begin to improve!
