ChatGPT Prompt for Sketch Drawing: 12 Looks to Try

A strong ChatGPT prompt for sketch drawing names the medium, subject counts, left and right hand actions, shading style, and paper look before any style adjectives. Use these prompts for graphite, ink, charcoal, and careful photo-to-sketch work on images you own. Lock lists keep the model from flipping hands or adding color you did not ask for. Below are 12 copy-paste prompts plus a flagship sketch compiler.
