This time we'll deal with the finishing touches; coloration, antiquing and wall mounting.
First of all, it is important to support the dry mermaid for the painting process.
I used a wire coat hanger which I bent out of shape and slid under its arms.
For painting the body, I mixed a small quantity of paint matching the fish's color; I used burnt umber, burnt sienna, sap green, black, and gold paint to give a slight shimmer to the color.
I then mixed 1 part paint to 3 parts latex, and watered down the mix a bit so it goes on more easily.
Don't worry if the resulting paint is pale, it'll dry much darker. The great thing with this paint is that it won't be uniform; since it's translucent, there will be some natural variation in the color. This is a good thing if you want a realistic paint job. Also, cover the whole fish, not just the body.
