Just relax and enjoy it. Listen to the music and join in. Maybe try standing up and moving, just to release some of the tension.
I'd watch the angle of your left wrist. As you move up the fretboard, the angle is getting a bit sharp - by far not the worst Ive seen, but its a big red flag personally. Ideally your wrist should be as straight as possible. You're young enough to get away with it for a while, but that means you should have 50 years of gigging ahead of you and as many of the old guys on here can tell you, one day in the (hopefully) distant future you'll get a pain in your wrist, and that's a very bad day. With treatment (up to and including surgery!) the pain can go away, but keeping your wrists straight and comfortable now is a much better solution.
