From the bottom up:
Initial sketch layer. This one is hidden once I’m done tracing the ink
Base colour layer. If there are colour gradients I put them here, such as the stripes on the tail and the pupils.
Multiply layer. Used for the shadows. I like the look of the abrupt shadows instead of a soft shade.
Screen layer. Used to brighten up some areas. As opposed to shadows, I like to make smudge these for smooth transitions.
Screen layer 2. Normally I put the highlights with the first screen layer, but I decided to keep them separate.
Ink layer. Black lines traced from the initial sketch.
