A pen sketch that gets up and moves

Latte's caption is "kinda bored, just messing around with a pen." The clip was made with Seedance 2 on OpenArt. A drawing starts to move.

That casualness is the constraint. A pen sketch has a line that is supposed to stay a line. When the figure gets up, the motion has to feel like it came out of the ink. Otherwise it is a character who happens to have been drawn. The boredom is the setup. The performance is the test.

The pen has to stay visible inside the movement.
