I couldn’t tell you what medium this is - I started using a mystery black stick in my art supplies. It was almost a fusion of conté and charcoal. I liked it and by the end I was pushing around a 1 cm flake. But it made it, which is good because this was a real life art assignment. I had to build/make a diorama first which I based off my houseplants and then constructed it out of various papers. Some things had to be made 3D and some flat. Then we were instructed to draw a somewhat abstracted version of our model and reverse certain objects i.e. 3D becomes one dimensional, one dimensional becomes 3D.
