Drawn for the ~Mermafied club as an interaction idea between Mira and a member of the species she's based on, the ornamental carp (nishikigoi in Japanese). Both Mira and the butterfly koi seem happy to meet each other! ((Mira is a butterfly koi with asagi coloration.))

EDIT: Uploaded the colored version, which replaces the original pencil sketch. This is probably the most complicated coloring job I have ever done in Photoshop. It took several hours and had to be completed over the course of two or three days.

I might go through and add highlights and a background later.

EDIT again: Uploaded a larger and higher-quality version because I was too sad that you couldn't see all the detail. Full view please!
