While related to the common household cat, leopards are really quite different - and not just because of their size. Leopards are powerful, predatory hunters, and their body type will be more muscular than a regular cat, or even a similar animal, such as a cheetah. Leopards can be drawn with the same basic features as a cat, but the details are what will help distinguish your drawing as a leopard.
Draw a single, long line that will guide your drawing from head to tail. This is referred to as an action line.
Draw a circle at one end of your action line. This will represent the head. Draw another smaller circle within the head, near the bottom. The smaller circle will help you draw the muzzle.
Draw an oval along the action line to represent the body. Sketch two circles inside of it, one at the front and one at the back. These will represent the shoulders and hindquarters. Use your guides to sketch out the leopard's powerful, muscular body.
Add in details such as the eyes, ears, whiskers and spots. Draw two rounded semicircles for the ears. Leopards have rosette-shaped spots, as opposed to a cheetah's thumbprint spots, and have white lining beneath their eyes.
Cover the body and tail with spots. Make sure the tail is rounded to the tip, like a cat's tail.
