This has a very nice development throughout the song with also having a nice change up in the latter half. However there is also room for improvement. First thing is the general volume of the different instruments and how they interact with each other. While the piano sounds nice in the beginning and in the more quitter passages, it feels very much drowned by the strings and almost lost. So it needs to either play way louder or change its register to get heard better. My recommendation would be to change its register to also have a more varied sound throughout the song and winning some more expression, which would be my second thought of improvement. While your instruments don’t sound bad at all, they lack quite a bit of expression. Mostly due to not using their expression for creating crescendos or decrescendos or changing their dynamic throughout the song. I feel like this could be a big way to embed more of your vision and let the listener feel and hear it more. It would also help creating more interesting textures like in the beginning strings where they could interweave more. Nagging aside, you did quite a good job that was lovely to listen to.
