Don't come near her.

My friends and I had to make a mythological story as a teamwork in literature class and we made it about mermaids. I'm not going to post the story here but it was about a mermaid who tricked you pretending she was a sick lady and she needed some help.
This is my first attempt of realism, I still need a lot of work and improvement! I need some advice, please feel free to help me in the comments section
I need to fix her left hand, it looks akward and smaller than the other one, I noticed it after scanning it, but I felt lazy, so I decided to do it later xD
