I started with the rough idea, chubby Santa sitting on the floor, texting. Really simple shapes. Piles of presents, a conveyor belt backing up, a frustrated elf.
Then I just jumped in, rendering the shapes, making line weights, and coloring.
Fun, but it's just too much. I added some brush layers to separate the distances, some brush strokes to make it feel a bit less Adobe Illustrator-plasticky. And I decided to ditch the conveyor belt. Too distracting. This makes for an overall clearer, stronger illustration.
