Here is a colored version of this image that I colored with Prisma Color pencils. I start with the lightest colors first, then layer in the shadows on top, and use a darker color for each layer until I get the depth of shading I want. Then I used a blending stump dipped in Mineral Spirits to blend the colors together.
Many people requested that I make the little Herbert and Bigsby Blinkie into a stamp. Here they are! Enjoy :-)
