Realistic backgrounds or animated?

This may be out of context but, the theme i’m going for are summery colors, (not sure if summery is a word but whatever hsdsg) but most the bgs i have are black, and i really took at least 1 month to gather all the backgrounds i have, so how can i make the story match the aesthetic i’m going for with dark bgs? :pensive: :raised_hand:
(i hope i made sense)
