Step 6: Draw two more connected lines on the top left side of the body as a guide for the goldfish's dorsal fin.

Step 7: Draw a triangle-like shape on the bottom part of the body as a guide for the goldfish's pelvic fin.

Step 8: Draw a smaller triangle-like shape on the lower left side of the body as a guide for the goldfish's anal fin.

That's it for the initial sketch! From now on, press harder with your pencil to get a more defined sketch.

Step 9: Draw the goldfish's eye inside the arc, close to the tip. The eye is basically a circle. Draw it lightly at first and darken it once you get the shape right. Draw two smaller circles, one inside the other, to detail the inside of the goldfish's eye. The innermost circle is the pupil. Shade it in using a dark value.

Step 10: Use the tip of the arc as a guide to draw the goldfish's mouth. Draw a small line at the top for the nostril. Then use two short lines to the right for the upper lip. Draw a wavy line under the top lip for the bottom lip.
