Your interactive drawing

(prepared for imminent failure)

You are a frustrated artist, you always wanted your works to be perfect, for your canvases to seem alive, for your art to be recognized as if the drawing could see its creator, you had this strange fantasy of wanting to have your drawings alive, for them to speak to you

You are walking on a rainy day when you enter a place with magic items that catch your attention; you find a paintbrush.
The ink never runs out...
The owner of the shop, a kind-faced old lady who sold you the brush, said that you arrived and washed it, wanting to start drawing. You were making a character (describe it, okay) when suddenly it/she/it moves and touches its cheek
Hey, that hurts...!
You could hardly believe it, your drawing has come to life
