SketchAlong

FaunaFocus recently focused on the spectacled bear during another SketchAlong. During a Twitch livestream, Noelle M. Brooks led viewers through exploring the proportions and anatomy of the spectacled bear. Starting with a full-body illustration, the study was then guided through the unique facial differences between several bear species, and concluded with a close-up of the bear’s enormous paws.
