Hi Class! If you want a closer look at the illustrations I made in the tutorials, including the time-lapses at the end, check them out below! I finished all of my illustrations using brushes from my Gouache Paintbox - mostly the Painty Round brush which you can get for free as a part of Procreate's All-Star brush pack.
My favorite is that ferret. I used the Shaggy brushes for that one. Then I used the Combed brushes to add some additional hairs.
