I started with a study of Tom Hollands face, then I inked that and went onto costuming that same sketch and inking the spidey side. From there I set up the base colors and built on top. I started with for shadow, then cast shadows, warmth, reflected light, highlights, and details. Then I had to finalize the background and design the webbing.
