30 Day Monster Girl Challenge: Day 5: Mermaid

This was going to be some sort of warrior, but then I decided to make it a koi-mermaid. And, after some research I found that koi are non-aggressive omnivores- they eat anything that won't eat them, which meant that there would be no reason for her to be in battle garbs. And sorry for any drawing mistakes, it appears once again I have no idea how anatomy works.
