Step 6: Under the mouth, draw a line that curves to the left for the bottom part of the dolphin's body.
Step 7: To the left, draw a line similar to a tilted letter V for the dolphin's first flipper. Curve the left end of the line a bit.
Step 8: Draw another V-shaped line on the right for the dolphin's other flipper.
Step 9: At the top, extend the line for the head toward the left to create the top part of the body. Sketch lightly at first and only darken the line when you get the shape right. The longer the line, the longer the dolphin's body.
Step 10: To the left of the flipper, draw another line for the bottom part of the dolphin's body. The two body lines should almost meet.
