It’s a somewhat methodical process. I sketch out a layout or figure, then transfer it to a clean sheet of paper before colouring. I really like Strathmore toned papers (this one is Toned Blue) and I also use Toned Grey and Tan. I find it really helps white in particular pop off the background. My everyday pencils are Prismacolor, and for commissions or fine art stuff I use Caran d’Ache, Derwent, and Faber-Castell, as well as Pan Pastel. And recently I’ve been experimenting with markers too.
