Hey, nice song, I could feel what you intended the listener to feel.
I really like the main theme with the piano, it's really relaxing and calming (or chill).
At 1:20 I found that the electric piano (I think that's what it was) did not fit too well.
It shows up at 2:57.
After listening to those parts again, I find them okay, but their sound does kind of break me out the calm feeling for a bit.
I think the end doesn't really require the keychange, but it works with it. It's a little hard to hear the main theme with the synths as well.
Overall, good job, and keep up the good work.
