I do like that shot, Andy. Some tough love there from Terry, though! And he's a pro and I'm definitely not, so treat our various comments accordingly!
These days I've only got a laptop screen to view, and I find a 1024-high portrait image very difficult to take in. It's a pain scrolling up and down. Luckily if I click through I can see it all on flickr.
EDIT: I meant to say here that on the TP version there seem to be some sharpening artefacts round the middle distance rocks. I don't see them so badly in flickr large though. /EDIT
This shot has a lot of different elements, and I'm not sure they connect all that well. The out of focus thrift in the foreground I don't mind at all; it is dark and obviously there as a framing element. The star of the show is that wonderful roiling mass of water in the middle foreground. However, my eye is getting drawn away to the rather muddy sky, where it stays for a while trying to figure out what's going on up there. I don't think that sky really works, but I think there's an even better image in here somewhere. I think I can see a crop that loses some or all of the sky (in which case the headland to the right becomes more valuable as a downwards leading line), but you may see another. But IMHO if you can get that boiling water to become the eye's focus again and again as the picture is inspected, you'll be on a real winner!
