Any advice on how to check if the robo bean exercises are correct? How to spot mistakes when the only thing I can see at the end is binary feedback "yes, it looks good" / "something is clearly off"?

Hi everyone! First week of mannequinization, one major problem I notice is that if there's tilt or twist in a pose chances are I'm gonna make it straight(er). Are there any other major things to point out? Thanks to you all
