Josie, That must have taken a long time to get that drum part like that. Great vocal! I would have brought the vocal up and dropped the cello volume.
I'm on my second listen. I think maybe I would bring the cello in and out to compliment the beautiful vocal even more. I would also consider a second acoustic fingerpicking, like counterpoint. If you do go back don't touch the vocal except a volume bump. I really liked the write and the melody. Nicely done! Tom
