The pre-programmed child in me just looks at the colour scheme you used here.
Fred's colours look really bright and heroic, while Miri's look darker / purple and almost villainous. The vest almost suggests evil scientist. :B (lolol jk)
I know she's not meant to be a bad buy, but if I were a little kid, colour would suggest a lot. Still - I like Miri's new outfit. Fred's pose is my fav too. B:
