In the original sketch, she was blowing bubbles, which was very cute. But while I was coloring this, I remembered that this pokemon can spit ink, so I replaced the bubbles with ink. But in retrospect, I miss the cute bubbles. When I colored her front, I didn't use a solid color. Instead, I used a Photoshop brush with a soft edge and low "flow" setting. This allowed some of the blue to show through, which I think gives it a very organic look.
