🎨 Enhancing Artwork with Stable Diffusion WebUI

This segment introduces viewers to the process of refining a piece of art using the Stable Diffusion WebUI. It starts with examining the parameters of an initially generated image and making two additional outputs for refinement. The latter part challenges AI's capability in art creation, specifically highlighting issues common in AI-generated art, such as distorted hands or the inability to draw characters eating ramen. The solution involves a series of steps starting with creating eight images from prompts, selecting the best out of them, and then making minor adjustments to produce ten candidates. From these, a final image is chosen, upscaled, and refined to enhance quality without starting from a large-scale image.
