Might as well call it Star Requiem :)
This is totally cool, the composition is awesome and I loved the idea of using the piano as the main melody along with guitar as a rhythm! but its a bit too predictable dont you think? So how about we add more variations and a bit of stuff to yk kinda throws the listener off a little, then get right back on it? It'll way be more entertaining imo!
You could put more work into mixing! The most obvious one i'd like to point out is that i feel like there's way too much unnecessary lows that kinda makes the music quite muddy. If you were to cut and gain some frequencies some more, i'm sure there'll be alot more rooms for other things.
Other thing i wanted to point out is the panning messes with me a little. I think its because the amount of imbalance in the mix. It felt like much more things are going on towards my left, abandoning the right. This is a perfect situation to add more stuff if it kinda feels empty!
Other than that, this music is great as it is!
