How to draw Pisces easily?

I have the following two painting methods for reference.

The first painting method is very simple and is used by many people. Is to draw two fish swimming relative to each other

The second painting method. Draw a beautiful mermaid princess. She sat on a rock by the sea. Keep an eye on the direction of the waves.

This kind of painting is a little more complicated, but the use of stick figures is not complicated, mainly different.
