Dear god...
That piano intro was completely and totally godly, but then you destroyed the song with the second half, because, I'm not gonna lie, it wasn't that good.
But the piano part was absolutely amazing. I thought I had died and gone to heaven when I heard that. You should definitely do a song like this except don't use a regular synth for a lead, use a piano. Actually, I think I'll do that...
Overall, I only really liked the piano intro. You should really work on your choice of synths. Seeing as this is a soft and sad song, you should have chosen a soft supersaw for a main lead, and a softer kick, along with softer synths all over. Again, nice piano work though.
