Here is Australia!
I recently learned what a color comp is. I think "comp" stands for "composition." But I prefer to call it a "color sketch" because that is exactly what it is! Color sketching was a useful tool for this illustration, and I am looking forward to making it a regular practice.
I made these 2 color sketches to determine the color of the sky. I originally wanted to paint a pink sky, but the color sketch revealed that the pink sky would wash out the colors. The color sketch with the blue sky gave a wonderful contrast with her red hair and added depth to the composition.
I also learned that Koalas have two thumbs! Maybe you just did too : )
