I'm liking what you got here. The piano is very nice especially.
But there's not a whole lot going on in the song. You set up a nice framework there, you should cascade into a climax. Throw some harmony on that bad boy.
Or you could consdier the piano harmony and put some melody on there, your choice.
It just needs to build.
I will try putting a Choir and some layers of different strings and others. And i would like to try to change the piano melody at the end. Thanks for the review!
