Very touching!
I really enjoyed this piece a lot! Especially the melody around the 40 seconds mark was pretty enjoyable. Great tune!
I think other people mentioned the recording quality already. If you're going to re-record I'd suggest you to record with a two mic setup, one directly in the piano (at the outside towards the hammers) and one directly at your player position to capture the room. This will help you within the mixing progress. Now I'm not sure what kind of equipment you're using but I'd also suggest to avoid clipping by lowering the mic input volume or using a limiter if your mixer allows that.
Just a few tips if you were going to re-record it. I'd really go for it, it's definitely worth it!
