Lovely tones and light Rob and the composition works very well I think. The halo around the masts is a bit disturbing though. Would a control point on the clouds in Viveza sort that?
I just had a quick try with the JPEG and I reckon it will work although you might need to do most of the darkening and change to structure at an earlyish stage in the PP. It's certainly worth a try though.
You have some really good tones in there. The red and blue are very nice although I found myself wanting the image to be brighter. However, the Vue Cinema image I like the darkness.
