Really. Speaking as an artist who has a lot of anatomy and Photoshop knowledge, many of these are... unrealistic in a way that gives credence to the fatty cries of "well they're just sexist!".  When you lose weight, you lose boobs and hips. It just happens. There is no way to maintain giganto fatboobs on a human body. If we're trying to show them what they could look like, let's not make them into actually unrealistic fantasy women, please. Size them down proportionately so they have nothing to argue against!
