Oaxacan Bearded Dragon: color palette and study!

^ My color palette for the Oaxacan Bearded Dragon includes purples and oranges, one of my favorite color combinations and based partially off of Draco's natural markings.

^ Rough color study to help me decide on color placement.

^ Cleaned up sketch, proportional to 9" x 12", referenced from several photos of Draco.

I'll have you know that bearded dragons' tails cannot bend like that, but I'm enjoying some artistic liberty for the sake of composition.
