The first drawing I fully rendered in color was of the howling coyote in the North American Mammals hall. This Canis Latrans diorama features Yosemite National Park viewed from a bank next to a stream. The painted background is breathtaking and melds seamlessly with the gravel in the foreground, making you feel like you're actually outside. The artwork inside the dioramas at AMNH are true gems and masterpieces in and of themselves.
But I didn't draw any of that of course.
Pat walked me through the general process: lay down the mid-tones first, then the darks, then the lights. Adding the last bit of white (especially around the muzzle) was especially satisfying. I've come to know that drawing fur is quite therapeutic.
