The same model, a different mood.
Yesterday we were very classical, looking back to early renaissance paintings, where the sitter holds an emblematic flower. Today's drawing continues to have that oil painting fascination with light and shade but using more of a fashion model pose - and a superhero mask. In my imagination, she has just saved the world and is being a little bashful about it, just wanting to get home now for dinner/put the kids to bed/whatever it is a superwoman needs to do next.
After all, she doesn't really have time to stand about being praised.
