Mermaids - Lissa

Been poking around with the idea of a mermaid story. I've wanted to do one since I was like, 10, but I've never really had any good ideas for plot or characters.
This is Lissa, she's a mermaid mage. She studied magic for a while so she could turn into a human, since she wanted to learn how to surf (which is rather hard to do with a tail.)
