Afterimage is defined "a visual sensation occurring after stimulation by its external cause has ceased." Sometimes I feel that all art is an afterimage, it's a visual sensation that is left after the process of creating art has ceased.
The green fabric at the top is a sheer fabric so you can see part of the image from the fabric behind it, also kind of an afterimage.
