I love the cello.
It was a genereally beautiful piece. I love the soft, mellow tone to it.
What you might want to do is louden the piano a bit, it's a tad too soft to be heard nicely. Plus it makes the cello tiring after a while.
I love when the two cellos come together.
I play the bass, I hope to switch to the cello next year :)
Nice ending, by the way. Sweet little piece. I think your girlfriend will appreciate this. I can so see it--you composing, she playing :)
