If you are communicating visions, emotions, feelings and other mental images then flowery is exactly what you need.

I don't agree, you can be explicit and simple while still communicating complex ideas- but it is a difficult skill. And an emotion is a generally a pretty complex idea.

I do agree that creative writing can be fun (honestly more for the reader than the writer, most of what I write on here was probably more fun for me to write than for anyone to read), but it is still just entertainment and not some sacred art form. I'll cope next time I hear someone describe some as "X gold". No, lithium isn't white gold, it's just an in-demand resource. Just say it's valuable if you want to. Analogizing something to gold isn't creative, it's an overdone trope.
