Aaaaand, here we have it! With the artist's permission, Cinnamon Sparrow's lovely Queen Otohime line art, as colored by me. Yeah, I know the official colors are already out, but since I started this before the colors were announced, I didn't want to have to go back and change it.
After hearing that Otohime was a goldfish mermaid, my mind totally went to the first pet fish I ever had (a goldfish), as well as certain types of koi with the same coloration as that first fish: red/orange and white. So, other colors aside, that was the general color scheme for my guess. The rest of the colors were mostly just because they looked nice (or because I couldn't think of anything else).
With that said, I hope you like it ^_^
