This is a doodle I drew while on a long phone call.
I had intended to draw a whole forest scene, complete with boulders, rolling hills, a little stream, bunnies, the whole thing. But I stopped after drawing the first line of trees. With the white of the rest of the sheet of paper, it looked like the edge of an interesting forest at the top of a snowy hill.
The lesson here being: learn to quit when you’re ahead.
