I love the concept - playing the same theme at different tempos on different instruments. It just... doesn't sound very cool, you know? Maybe if you were to go away from the piano and try some different sounds... and maybe experiment with different keys too, but you may kick that idea...
I love the concept. It's creative. You just gotta push it a little more
thanks yeah i could of experimented on it more like you said added a few more things to it.
but it came out ok:)
