I've had this mermaid a while, but couldn't come figure out how I wanted to use her. Here's what I came up with. I used Taken with Teal and the Bali Breeze Designer Series Paper from a while back.
I used large pearls in the center of her crown, then gradually went smaller. I colored her hair with SU! Watercolor pencils, but the rest I used my blender pen and ink pads. I coated her tail in some sparkly Dazzling Diamonds glitter.
