Hi,
Are you rehearsing for a public performance? If so, then I'd say it's good and ready to hit the local farmer's market on next Sunday : )
Just a few quick observations:
The middle player should not glance around especially at the side players because they don't glance back.
If there is a desire to look at the audience, then maybe consider not having the music up because you'll likely lose your place in the music anyway. If you need the music, then better to just look at the music instead of the audience.
Supposedly making eye contact with the audience is tricky to make it look natural. The last thing you want is to look like you are worried about a cop showing with an arrest warrant : )
Is the big ukulele a baritone trying to supply a bass beat? If so, I can't hear any of it (but I'm on a laptop with tiny speakers).
I'm not a very good live performer so I get a lot of tips from good players. So, take the above nit picks as coming from a nonexpert at implementing any of them.
Overall, a good performance; I really enjoyed it. Thanks for putting it together.
