That stick figure is slaying that mirror pose!
I liked the main instrument you used a lot but i think the percussion felt out of place with them. Specifically the snare drum. It felt a lot louder and faker than the rest of the instruments causing it to stand out to me.
I really liked the ambient noises like the birds and water a lot!
Hmmm, I think the kick fits well but the snare and hat had a lot of high-frequency information that the piano doesn't have. I'd consider putting a low pass filter on them but if that doesn't sound good, try a vinyl VST like Izotope Vinyl or a tape one like CHOWTapeModel to tame the high end. All of the percussions were significantly louder than melodic instruments, so perhaps you could lower them down and use sidechain compression for them to still cut through?
That was long haha sorry I just wanted to spitball some potential solutions that came to mind!
