Saturated Canary is one of my favorites.
I had a lot of fun coloring her, and to give her tail that extra scaly appearance, I used mica flakes. They are very tricky to work with, and you need to use gloves or you might cut yourself on the super thin pieces, but the effect was really neat. Experimenting is fun.
I used her on a birthday card I made for my friend, Dani, who is quite possibly more into aquatic life than even myself.
