The melody is just amazing. I've always loved the piano. You did a very good job. The only thing I would suggest is perhaps somewhere in the song change the tempo, make it a bit faster. Also work on the percussion. The drums are too plain, and too slow to really get any rhythm out. I would love to write to this sometime.
If you're up for a collaboration I would love to remix this as well.
Other then that, this piece is wonderful. Keep up the good work.
