I think the way to draw a shark is as follows:

1. Use a hook pen to draw two arcs to form the body of the shark.

2. Draw three triangles on the shark’s upper lip to represent teeth.

3. Draw a diagonal line and a semicircle next to the mouth to form the eyes.

4. Draw three vertical lines on the body to represent lines. Draw the fins on the top of the body and the wings on the bottom.

5. Draw a triangle on the tail, then connect two semicircles to form the tail, and color the shark blue.
