Then comment on relevant things, not beginner stuff like how much I pivot. I know what I'm doing. It's pretty insulting hearing from guys who don't box (or suck at.it ) The equivalent would be me telling a judoka his throw was wrong because it was not a hip throw. There are several ways to throw a boxing punch, some which beginners won't even think is boxing. Watch matches closely and you will see the variance
Better things to comment For instance: if that tactic would work in sparring,why it wouldn't etc.
