I adapted this well-armored dragon head from a development session in Peffer's book. She likes dragons with horns, which I think is kind of superfluous, especially since these cattle-like horns sweep backward from its head rather than forward to menace its enemies. This dragon also has fin-like additions to its exterior, suggesting that it may be able to swim as well as fly. Fortunately, there are many species of dragons, so if you want to envision one that looks like a giant armored goose, it would make perfect sense. Most dragons have adaptations from many different groups of creatures all together: reptile, bird, and mammal.
The sketches represent a smaller and more traditional dragon species, with graceful figures and bat-like wings. I drew much of this page with a wide-lead pencil which allowed me to do broad shading effects and varying line weights.
