A graphic design for my documentary poster

I want a “movie or like preview poster” designed for my documentary that’s coming out called “finding sunshine in the rain” I want something similar to what you would see for movie preview ads with the title,director, Etc. I wanted to try to create something like a realistic image of like half sunshine half rain with the title or like something creative to portray it. The documentary is about mental health. I’d be happy to elaborate more if needed.
