It's a nice piece, but I feel it is a little repetitive. And isn't this more techno than classical?
Anyway, the piano part is way too repetitive, and it just doesn't satisfy. Also, try to work on the dynamics, especially in the piano. A little more harmony in the piano part would be nice too, especially in the left hand.
I can see what you are trying to do with this song, and it isn't bad. I just think you could take it up a notch, especially on the piano, considering that is mainly what the song is made up of. Try to add a little more variety and expression.
Not bad, but not the best. 7/10
