More crosshatching.
And some markers.

(Mind!World blurb!)This is The Black Dragon: physical manifestation of magic and chaos and all things unknown. And I would just like to strongly emphasis, for all his crazy mischievous schemes and manipulations, he's not evil. :|
As a Greater Dragon, he's supposed to have eight limbs (six legs, two wings) but the wings would be unwieldy here so I didn't draw them in. Instead, he gets a starry sky backdrop, seeing as the night sky is his wings.

Yep.
