Using Stable Diffusion and Textual Inversion to Create Stylized Character Concept Art

Learn how to create stylized character concept art using stable diffusion and textual inversion in this 36-minute tutorial. Explore the process of generating style embeddings, sketching base characters, and using img2img with loopback scripts to produce variations. Discover techniques for refining images in 2D software, including masking and painting. Gain insights into checkpoint merging, prompt crafting, and image finalization techniques such as sharpening, adding bloom, and applying painterly effects. Master the use of tools like the spot healing brush to correct irregularities and enhance your digital artwork.

I'm not using vanilla standard diffusion 1.4 checkpoint for my textual inversion training model or img2img. The model I'm using is a 0.5/0.5 weighted sum split between standard diffusion 1.4 and waifu diffusion 1.3 not the final 1.3 model. I go over this in the video at timestamp .
