Illusion of Space 2

Its basically decided, the Illusion of space in a drawing is making a 2D artwork look 3D by adding up bigger images in the front while adding smaller images in the backround. This gives the picture the illusion that its popping out of the paper. In this art of mine She is stepping out of the painting onto the boys back, using him as a stepping stool. it shows on her legs the illusion, one is still in the painting while the other is fully out. Her dress also shows the illusion the same way by some of it in the painting then some of it out of the painting as she is stepping out.
