My brain keeps fritzing when it comes to

My brain keeps fritzing when it comes to the girl in the back and Witchblade girl in the centre.  The girl in the back’s far breast looks like her shoulder sometimes… and Sarah’s breast looks like an elbow to me and her hand is on her shoulder.  And then my brain will see it as a breast… then back to elbow…  This is like that picture where you see 2 faces sometimes and sometimes see a cup! xD
