I'm really glad Sean wrote that Dorothy punches the Lion. It would never have occurred to me to make that change, and it makes for a much stronger character moment than the slap. I mean come on, she grew up on the mean plains of Kansas.
I thought going off the Denslow Lion would make it easier for me to draw him, because I'd have all this reference I could look at. But there are some WILDLY inconsistent profiles going on with that guy in Wonderful Wizard.
