Hi. As far as i remember, you have to draw a straight line from the head to the ground. If one of the legs goes over this line it feels like is going to fall. You can take that in practicar in real life (which i dont recomend) but you will fall.
Ohh, I forgot about that trick, thank you! :D
You’re welcome :)
balance line is a good check. idk if the legs are the whole thing though, the hips look pretty flat to me. maybe tilt the hip box a little so the weight sits on one leg and the other knee can bend
