The head at the top right and the figure on the bottom right are from the story A Taste of Fertile Soil. They’re versions of a sort of otherworldly gardener. They hunt invasive “weeds” and removes them from the garden. In the context of the story the garden is the human race.
On the left we have our standard anonymous practice drawings. Pompadours are fun to draw. Never actually tried to wear one myself. I tend to favor the shaggy look.
