Positive Comments: As I was listening to your beautiful guitar riffs, I couldn’t help thinking of the old Bread song “If a picture could paint a thousand words than how can I paint you’. Same vibe. Really nicely done.
Constructive Comments: You changed from a guitar to keyboard @ 50 seconds. It took me a second listen to realize that. I think you should have stuck with the guitar throughout and used the piano and other stringed instruments as backup harmony. The best way to explain it is the change in the lead instrument from guitar to keyboard changed the mood / ambiance of the score if that makes sense.
