The only thing I would comment on is the tyrapping of the conductors.
I hear you Pierre, I agree I am not a big fan of tie wrapped panels either. If I go back to that panel I will cut them off as at that point the conductors will have taken on the shape I wanted.
As you know stranded THHN can be tough to 'train' without tie wraps.
There is a violation in the bottom panel no one has picked up on.
