For free brushes, check out Loish’s Digital Art School! It includes my brush set with the brushes I use most often in all of my art. As for other brushes I use, my favorite sketching brush is the MaCaLabs HB Pencil brush, which you can download for both Photoshop and Procreate. My favorite Procreate brushes are MaxPacks Gouache and RazumInc pro II.
