A creative use of this tool.

new features of grease pencil (surface stroke etc.) suggest me some alternative uses of this tool.
some really useful when modeling or animation (we’ll later) other fairly useless but very funny.
like this.

I could say that this technique facilitates the sketch 2D
(position in space of stroke, lights and shadows etc) but in reality it is just “artistic”.
maybe some of you will find a more productive use!
