In regard to night time light, it should be pretty dark, but not so dark that you cannot see ship silhouettes, there should be enough star/moon back lighting unless in a storm. When out at sea in cloudy weather, you cannot see anything basically. If you are looking for anyone's opinion about your clouds kriller2, I like them, but I think they would look even better if you could blur their edges a bit more. This is just my opinion/observation fellas, your work is breath taking.
