I listened to the full gig and my only additional suggestion is to look at moving the capo around the neck. The guitar sound was very similar throughout the performance. Changing the position of the capo, or even playing in the open position, would mean transposing the chords so you're playing in the same key as your vocal.
It might be my ears but I'd have liked a little more low end in the guitar for some of the songs.
Feel free to ignore me if you disagree,
