Hello, I love Chopin's preludes, they are so great from a compositional perspective. Yours sounds nice. Perhaps there is still more to be written - just a rough sketch for now? More of a matter of subjective taste - I would have personally kept it non - minor a bit longer at measure 14 before going into your next idea. When you change the repeating note at measure 25, it feels a bit abrupt to me. For some reason, the G nat really sticks out. I don't know. A matter of personal taste again. Bar 52 feels very satisfying. I will share a video of someone else who has been inspired by chopin's rain drop prelude. Hayato Sumino - Raindrop Postlude
