I noticed something.
With the exception of two poses, May always puts her weight on her right leg. Now, obviously this means nothing, I do the same thing and this is a pretty standard "girl" pose but I'm a writer and that means I overanalyze everything so...
Headcanon: she primarily puts her weight on her right leg cause her left got injured while she was on her journey/helping her dad with field research so it hurts to put too much weight on it.
