Oh, that piano...
Your piano improvision was just simply beautiful.
For that reason alone is why I'd ask to take out the clarinet and the strings.
I feel like they drown out the piano, which is what I'm striving to listen to.
Don't get me wrong, it's a beautiful piece all together, and it's ultimately up to you what you do with it. But if you posted just the piano to this, I just wouldn't know what to do with myself. :p
Great work, as always.
