I've been trying to work out how to colour sketches in photoshop, and removing the colour of the paper without loosing the quality of the line. I'm starting to figure it out. I've been having fun colouring in these sketchbook birds.
I've also tested a few images using linework/shape. This one below is from my most recent story April Fools, I plan to use linework in this project.
Here is a combination of shape and line. It's a concept image for my book The Bug Banquet.
