8D I didn't realize until yesterday that I'd never posted this one...
So this is a final charcoal still life drawing from when I took drawing classes in college: The biology building's greenhouse was the scene. I tried to include both plants and machinery in it, since there was an abundance of both there. :D
And this drawing is large... 19x32 inches. ^u^ And I like the way it turned out, even months and months later. XD
