It looks like dragon scales to me. So that's what I'll call this piece.
Recently I went to the art store and saw watercolor postcards so I figured this would be great to make Artist Trading Cards. So I took out my watercolor set today and brushed away on the background colors and took out my sharpie and made the scales. This will be going out to Steve over at Go Flying Turtle. I had stated previously that I was going to send him an ATC for trade based on the doodles that I was doing. Sorry it took so long!
This was the inspiration from a previous post it.
I thought about blacking in like above. But the way the background colors were showing through looked pretty cool so I didn't.
