shadows and teacups

Lots to learn about shadows - how to mix colourful shadows, how to paint shadows in values 2, 3 and 4, or even 5, the difference between the shaded side of a building (which is often just a darker shade of the local colour, and which can have a lot of reflected light in it) and the cast shadow (which is normally darker); the existence of the terminator, such a revelation!, and lots lots more! I loved painting the white cups the best, I think. Although colour charts are one of my favourite things!
