I thought it would be interesting to see Stan's finished level 1 and level 2 side by side. It clearly shows that the shadow and light areas broadly established in level 1 are still very much maintained in level 2, despite all the extra details. The only part that I wondered about is on the left side of the head, sort of between the cheek and the ear: I kept thinking it looked almost like a halftone, not a shadow. So I tested it by copying swatches of tone and sure enough, it's still darker than a halftone. It probably feels lighter only because of darker values surrounding it. Also, I wanted to ask about the concept of "contained shapes" that Stan talks about around minute 17. The video shows a couple of examples of artists who use contained shapes but could someone please suggest some counter examples? Artists that use non-contained shapes? It might help to understand the concept.
