Karol did not go through a lot of redesigning, indeed it was already in mind from the start and was fart easy to work: baggy pants, hair style everything. but I did not like the first look, so I redid the sketch again, and voila, more closer to what was in my mind. Also, in the final idea, both Jack and Mary provided a bit on the final look - key items been her skin color scheme (which is Jack's, after all he is her father) and Mary via the Mushroom hair with the green lasso that holds it.
