Heads, hands and phones. Pencil outlines for the foreground objects.
My first reaction is surprise how BIG and GRAPHIC everything looks (this is a 3 foot canvas.) You plan a painting in your head, and you might mock up a version on your mobile or laptop, but it’s still something of a surprise seeing it large. I like how the various planes are crushed together, but hope the big head on the left doesn’t unbalance the composition.
