Maybe you should make it a bit clearer that the girl is battling against Lukemia? It's easy to see something's happened, but what that is... that's a mystery unless you first read the description. Feels like there's too much holding-head-in-hands and looking miserables when the girl doesn't even look dead at the end. The music works well, and it does seem a bit sad, but it feels it's not as effectual as it could've been with a backstory before the ending. It's just all... ending. Keep it going!
