Crushed Waterbottle - Susan Kim (Pencil Drawing)
This is a good example of VALUE because there are many different lights and darks throughout. You can also see a few shadows and highlights, which help make that drawing look more realistic.
Okay not a portrait but, If the artist's tools were not present in the image I would think I could take a drink out of this glass.
