Dragon skeleton! So I decided to try to come up with a reasonable shoulder structure for a six limbed dragon. Here's the front half at least--I'm not entirely happy with the results, but I was getting tired of picking away at in my sketchbook.
EDIT: Forgot to say that the wings are purely decorative. This dragon probably has a lovely mating dance.
And also, here's a knight jousting on a Gorgosaurus, the most serious of all dinosaurs.
