The melody sounds like you should drag it all down a bit. The beat is to silent. You can't almost hear it. Or perhaps I'm getting deph from reviewing all this crappy music ^^ .
I advice that you do a little remake
- More volume in the beat
- more volume in the piano
- less volume in the main melody.
- Violins are fine
Its a pretty negative review ^^ but it's only my intention to help.
