Since you are asking for advice . . .
I think the B/W version works much better. This has some presence and
gravitas, whereas the colour version is just sort of blue and feels to me more like a snapshot, to use a very pejorative word. The clouds are rather special, but I'm not really sure that they are special enough to make the picture
terrific, if you know what I mean. But there you go, that's advice for you
