A still life does not have to be a careful composition, it can also be messy. In this pile of toilet roll tubes, only one tube in the middle foreground is completely visible (that’s where I started). Of all the other tubes, you only see part because of the overlaps. This gives the still life a three-dimensional look.
Exercise: Draw one or more piles of toilet rolls/boxes/eggs/tubes/stones or other easy-to-draw objects. Let the pile(s) fill your entire paper. Color the objects if you want.
Here are four drawings by primary school pupils (approx. 10 years old).
