The idea is there, but this track needs a little more and some changes. Of course, this advise is personal and no guarantee for any success.
I would skip the piano “solo” or use a better piano. I really like the piano in the background (as a supporting instrument), but when you start playing it as the central instrument, the track looses its magic.
Also I would like to see some ‘build up’ in this track. It goes nowhere right now. Build in a break and come back with more power. Making it more epic, giving it a meaning, a proper ending.
