In the garden. Have her be sitting (last panel I drew) and look off in the distance. A strange mirror sitting in the garden (like pic I found, a rounded top mirror fancy looks misplaced). Walk up to it from right to left. Girl on right mirror on left. She sees 2D girl. 2D girl fills screen, sees the jewelry box on vanity. Carry on with the mirror sequence then PLUS I have the room. As 3d girl walked forward the mirror, more and more art nouveau. As 2D girl walks away even more stylized art nouveau with abstract screen space.
