Missed the first day but oh well. I decided to do a series of mermaids for this challenge! The amethyst mermaid is based on a bottlenose dolphin and has an amethyst gem in the crown on her head because amethyst is associated with the mind. Sorry about the bad quality pic though, my phone's camera isn't very good. I'll update if I get the chance to clean it up in Photoshop.

EDIT: Added wip of the cleaned up photoshop version
