Fight-o!
I was thinking that one of them could have the bleach blonde you see in some Yankees, but it made me realize that a huge part of their character designs are their hairshape/color and what clothes they consistently wear, and it would be practical to only change one to keep the character's clear.
Great work on the shoes, especially luz's doc marten's, and you really had fun with the Yankee style.
I would say willow looks really tall in her frame, but her build does look like one that has alot of room for growth, and lends it self to jokes like "willow popped up like a beanstalk" which makes sense as all the character look maybe 2-3 older, still kids, just now definitely "teenagers with attitude".
Thank you for making this
