Adding paint to a carefully drawn illustration.
Infusing the image with color--a pulse--but not being able to go back once you begin.
The pinks, purples, and blues are "loud" but I always lay in the most intense colors first then dull them down as needed (part of my "un-training" from art college).
Think of it as a blueprint for the rest of the colors to build upon.
The next step will be to block in the shadows and enhance the owl's coat.
Little by little it's getting there!
