Mountain lions have short fur covering most of their bodies revealing strong muscles below the skin. They have slightly longer fur on the belly, chest, and back of the legs that may form clumps with distinct cracks between them. Use a combination of the techniques you have seen for drawing animals with long and short fur.
Techniques to draw fur
Do not draw individual hairs, draw the pelt by showing the cracks between clumps of fur.
Suggest breaks in the fur or cracks along the contour or edge of the animal by strategically placing out-to-in flicks or “Bill Berry lines” where the contour abruptly changes angle or where the fur stretches over a prominent bulge.
Suggest the shapes of muscles below the fur with shadows and highlights.
If the fur is glossy like that of a horse, add sharply contrasting highlights.
