Here's a good chance to hone your monster cartoon drawing skills- just follow this step by step tutorial.
Step 1
Start with the eye. The head is a nice curve. The rest of the parts are a nice set of simple curves for the body, hands and legs. Add a couple of eyebrows. The eye and eyebrows add character to your monster.
Step 2
With an airbrush, colour the body. Green seems to be the preferred colour for monsters, but you can do them in other colours too.
Step 3
Using the pencil tool do the eyes and the spots on our monster. Voila! your cartoon monster is ready.
