A free sketch I did for  drag0nn. in my January Free art give away.

With their character they asked me to crate the rest of them from a headshot. It was crocodile, wolf, and dragon. So with used the crocodile snout, front legs and then the tail. Then to tie in the wolf ear I adds the back legs to be built like a wolf's. Then with the wings I made them short and tight to the body. The reason for that is the idea that it would be near or around water and the wings would act like huge fins to help push it through the water faster.

I had some fun with the challenge of thinking how would it be build to serve in real life.
