Build up forms
Next, I begin to lie in big forms. I want to find the anatomy of this creature. Because my beast has a skeleton, I’m careful to take note of where certain bones and landmarks are. I indicate key elements like the shoulder blades, the pelvis and the rib cage. These large forms will help me indicate where the muscles lie and help build a more believable creature.
Remember to keep it light! We want to build on top of this drawing as we go. I lie in bone landmarks, and get out my anatomy books, for cross-referencing when necessary.
