Just above the top of the long line of the hook add a very small dot for the eye. Starting at the short curve of the "J" draw a very large curved line for the back. Think of a big backward "C".
Just behind the eye add a short line to make the neck line. At the end of the neck line add a long, thin "V" shaped fin. The fin will angle back towards the back line.
From the tip of the fin draw the tail line toward the back line and then curve sharply down. Make the bottom almost touch the back line.
