Begining is kind of empty. I know it's a piano song but somehow gives feeling of bad production. Ambient synth/effect thing gives feeling of muddyness and it's too much on top of everything, especially in some parts of the song.. You could highpass filter on top of it
I would prefer more distinct bassline of either some low string or just simple electronic bass instead of that ambient synth
Harmonies are pretty interesting, bonus points for effort
