Black and White Dragon

The prompt was to create a black and white dragon that had been summoned through a spell. Not sure if I got the spell summoning bit right, but the client was happy with the dragon itself.
Speaking of which I'd like to take a moment to talk about said client. She writes a book called the Apprentice and every chapter is illustrated by a different artist (typically an artist will make anywhere from 4-8 images to add to the book). She's a really cool lady, and I love her to death. Thanks for the opportunity to work with you, Miss Christine Griggs!
