My friend Aaron Rix often colors my work when I am lucky enough for him to be available to.
I wanted to demonstrate the amount of work he puts into a piece like this by showing my line art next to his color layer, followed by the finished product. Painstakingly cutting, masking, painting, knockouts and color adjusts. My favorite of our collabrations thus far.
