The song starts off with giving a nice feeling but I really feel like this could've been much more. There was little to no energy change and I think it would benefited from sounding more dynamic. I think at the start you should make the piano sound far away with a feedback killer and increasing the room size on the sound. I don't know if they call it feedback killer on FL because I use bandlabs. There are other ways to make something sound far away but that's the way I know. There could be a better option so I think you should search that up for tips.
Overall I think this song has a lot of potiential and I wanted to see more come from it.
