While we were doing a project with magazines in art class, I came across a picture of a terrarium, so I took it with me and drew it!
I thought the pitcher plants would be hard, but they were actually a lot easier than they looked.
Also while drawing this I discovered that if you fold your reference photo on its perspective lines, it makes it easier to find the perspective point. That probably should have been obvious, but oh well, I know now.
