An image for my upcoming how-to-draw dragons book, DragonArt: Evolution, out this August 
The markings were originally going to be based off the Picasso Trigger Fish, but I deviated from that less than a third of the way through, haha.
You can view the work in progress on the NDA forums here: https://www.deviantart.com/neondragon/art/Drake-158413658
