I never really liked my design for the Little Mermaid I did a few years ago, So I re-did it! Let me know which look you like better, old or new? (old: katiealves.deviantart.com/art/… )
So on the left eye, I've got Ariel on the rock with the waves crashing around her. Then on the right eye, is the scene where Eric impales Ursula with the ship and she pulls it down into the water.
I originally had Ariel on the rock, just like it was shown in the movie, but you couldn't really tell what it was, so I had to add her tail.
