Step 6: Draw the guide for the arm on the left as a line that is a bit bent in the middle. Draw a small circle at the end of the line as a guide for Ariel's hand. The guide line for the arm on the right should be shaped sort of like the letter V. Add a small circle for the hand at the end too.
Step 7: Draw a curved line to the left of the torso for the top half of the guide for Ariel's tail. This line should be similar to an oval, only the left side of it should be behind the torso.
Step 8: Draw two curved lines on the left side as a guide for the bottom half of The Little Mermaid's tail. Pay attention to the length of these lines in relation to the rest of the body. If you make them too long, Ariel's tail will be too long as well. The two lines should curve up and come to a point on the left side.
Step 9: Draw two more curved lines below the tip of the previous shape as a guide for the first fin. These lines should curve downward and come to a point. They should also be almost as long as the bottom half of Ariel's tail.
Step 10: Draw two more lines above the tip of the tail as a guide for Ariel's second fin. The shape of this fin should have more of a vertical orientation, whereas the previous one was more horizontal.
