For a moment I was confused why Mao's clearly standing a little bit taller than Anzu, who is supposed to be 1cm taller. Then I noticed shoes v. barefoot and their difference in posture. Wow, this guy was meticulous.

I like that kind of attention to detail. Frankly, it bothers me when people draw characters against a height chart where their posture is clearly not completely straight up, yet they're drawn on the height chart as their nominal height anyways.
