So I just whipped up (read: worked on for 2.5 hrs) another picture to sell on Etsy. I'm wicked proud of how this one came out. My scanner has some color balance issues so I have to trick OpenCanvas into letting me fix the color but I think I've pretty much matched the scan to the original.
I used a similar design to my Little Mermaid girl. India Ink and Watercolor on Bristol Board. Yah.
