It does look better! To me it looks like your backswing is still a bit too long though. If your issue is consistency, I would think somewhere around here (maybe slightly further with a driver) is where you should be ending you backswing. Once you become more consistent you can start lengthening it slightly.
For me, the shorter my backswing is, the more consistent my shots are. I think shortening the backswing will also help with your left elbow not becoming so flared.
I recall a somewhat recent study that T-cell response was present in people who had been infected with Covid-19 with mild/asymptomatic cases, so the lack of antibodies doesn't necessarily mean that our immune systems won't have the biological machinery to fight infection, and eventual vaccination against this is not an unreasonable hope. While we wait, masks and physical distancing are the best tools at our disposal.
