I wasn’t too thrilled with the choices this month for the challenge, so looked around in the archives a bit. I really liked your arrangement and decided to learn it. I even ended up modifying a little bit, which I have never done before.
Your playing sounds great! There are just a few places to work on some transitions: practice the intro and the spots where you go higher on the neck a tiny bit more, and you have a great performance. If you practice these spots with a focus on hand position slowly, you can play with less or no buzz consistently. Keep up the great work.
