Step 6: Under the triangle, draw two lines as guides for the neck. Sid has a long neck, so make sure these lines are long.
Step 7: That’s it for the initial sketch! You have the basic Sid shape. Now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 8: Use the circles on the top corners as guides to draw Sid's eyes. Darken the shapes and add some lines above and below for extra detail.
Step 9: Inside each eye, draw a small circle for the irises. Inside each iris, in the middle, add a dot for the pupils and a tiny circle off to the side to represent glare.
Step 10: Use the circle inside the head as a guide to draw Sid's nose. Follow the basic shape of the circle as you darken the lines and create the nose. The top and right sides of the nose should be flat. Draw the left side using a series of quick, short strokes to represent fur. Inside the nose, near the bottom, draw a couple of curved lines for the nostrils.
