Step 6: Below the first circle, draw a small, V-shaped line as a guide for the beluga whale's flipper. On the left side of the body, draw a small, triangular shape as a guide for the tail fluke.
That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.
Step 7: Inside the head, close to the left edge, draw a very small oval for the beluga whale's eye. Inside the eye, draw a tiny circle and shade it in for the iris. Don't worry too much about the detail, as the eye is too small for it. Draw a few short, curved lines around the eye for some wrinkles and skin creases. Draw a few more short lines higher above the eye to emphasize the structure of the thick brow.
Step 8: Near the bottom of the head, draw a wavy, horizontal line for the mouth. The beluga whale's mouth should be close to the eye on the left side, and the right side should stick out of the circle a bit. Below the right tip of the mouth, draw a short, curved line for the beluga whale's lower jaw. Above the mouth, draw a slightly longer curved line for the upper jaw.
Step 9: Use the initial circle as a guide to draw the rest of the head. Draw the top, right side of the head farther away from the circle for beluga's distinct bulbous head. Darken the top edge of the circle and the guide on the left side. When you darken the bottom of the head, draw the line inside of the initial circle for a skinnier shape. Draw a few short lines near the middle of the head to emphasize the structure of the mouth.
