Thanx for the comments,
well I started played 2.5 years ago when i was almost 16.( If anyone wants to know)
And about the tempo changing this mostly what I wnat to do , in almost any piece im playing im doing it to raise the drama of the piece.
and about the linked you added about your preformance, I think its a good one, but you need to record it on a real piano in my opinion its different you know.
