Here are the two images with colored pencil treatment:
(I'm using Dick Blick colored pencils. I have the 72 pencil set, lots of rich color choices and of a good quality for blending - even on cheap copy paper - and very reasonably priced.)
I'm fairly pleased with the look. Of course, watercolors won't be exactly the same. I'm not talking about wet vs. dry - this exercise is about finding the color not texture. I'm talking about how my paint pigment choices are different from my pencils, but I expect to be able mix good approximations using these pencil mock-ups as a guide.
I've decided not to fill in backgrounds this time, not even with a light wash. I don't want anything to compete with the definition of the characters. I may ink in more detail after the watercolor treatment, which I'll start tomorrow...
