Groups of objects
For this exercise I had to draw groups of objects of different shapes and sizes. I did the first image in A1 with willow charcoal. I focused on the volume of the objects, their distance from me and from each other, the negative space between them and their transparency (or lack of). The cylindrical shapes were a bit challenging and took me a lot of observation to get right. It was very enjoyable to practice drawing shapes without having to focus on the details or in light and shadow.
After the above drawing, I still wanted to keep practising so I kept drawing groups of objects in my sketchbook.
