Here are the color comps that I had whipped up in Photoshop for the zoo mural art.

I ended up picking the bottom left colors for the
final piece, which was done in concentrated dyes, gouache & color pencils. I think color comps are a great way to lay out any value/hue issues before getting to the final. In this particular piece I only varied the background color because I decided to keep the animals colors naturalistic (so there were no confusion as to what was what).

The illustrator link of the day is
Genevieve Kote, who is from Quebec City. She does a lot of freelance stuff, mainly for publications. I just love the whimsical characters, well-planned composition, and bright color schemes that she executes in her illustrations. She also has a great ability to depict any situation in a light-hearted, yet not overly-comical way.

She also has a
flickr which has more up-to-date sketches &pieces.
