To create it, I started by making a blue-green watercolor background. I sprinkled rock salt on the paper to lift the color in areas. When it was dry, I photocopied it so I could try several tangles. Also, the photocopy paper is slicker than watercolor paper, so it provided a surface that would bleed less.
The waves and shells were done with sparkly ink pens. I colored in my waves with pencils, then applied acetone to smooth out the color. I did the same on the sea shells.
The green plant was made by layering green leaves that I cut by hand.
I drew the beta and its fins. You can't really see how glittery the image is, but the sequins and glitter do add a bit of pop.
