I think moon reflection wouldn't look like that. It should be wider and wider coming to our direction.

I ment to add some silver lines over the top of the train, clouds, rails... Not from the other light sources, but from the moon only. I want to say your constant moonshine is not bright enough. It's just an IMHO.

Thank you! But I have a question, if you don't mind: What do you mean by "contrast highlights"? (Sorry if I am asking something obvious) Do you mean I could have added other small light sources here and there to break the monotony of the constant moonshine?

I would rather add some tiny contrast highligts everywhere...

Anyway, you are really good at dark night exposition, I must say.
