This is breathtaking, the most beautiful I've ever seen you do, first this material, is it black clay? Because you can easily manipulate it like a pencil of a sort in other to draw on that white canvas.
Wow from a dinosaur to a deer, to man's ecological system if I'm right, the artistry is more than amazing the way you were able to create something out of nothing is the most determining factor. I'll like to see you explore more drawings with this. Well-done
