In the upper left, Demeter stands, arms open wide to welcome her daughter back to the world of light.  Demeter stands in the opening of a cave, a clouded sky behind her. 

Inside the cave, Hades stands, one arm supporting Persephone.  Hades is wearing a flowing blue-gray robe with a white cap on his head.  Hades appears as a handsome young man with curly brown hair.

Persephone is leaning toward her mother, standing on tiptoes, arms outstretched, head back, looking up at her mother.  She wears a sheer white gown through which can be seen her naked form.

At the foot of the cave, near the entrance, a few flowers can be seen growing.
