Donovan demonstrates how to turn a hand-drawn robot sketch into sticker art using Midjourney. First, upload the sketch and copy its URL link. Then prompt "/imagine [link], robot sticker, white background" to generate variations.

Prompt modifier to know: --niji which creates Studio Ghibli style renderings.

Use modifiers like "-r3" to create multiple options and pick the best one. Refine the style with words like "cute" or art directions like "Studio Ghibli style." Describe the intended use, like "sticker," so Midjourney provides the right format. While some trial and error is needed, this method unlocks the sketch's potential.
