<h2 id="overview">Overview</h2>This LoRA aims to make Qwen Image's output look more like images from an Illustrious finetune. Specifically, this loRA does the following:<ul><li>Thick brush strokes. This was chosen as opposed to an art style that rendered light transitions and shadows on skin using a smooth gradient, as this particular way of rendering people is associated with early AI image models. Y'know that uncanny valley AI hyper smooth skin? Yeah that.</li><li>Generates women with flattering proportions. Wide hips, slim waist, etc.</li><li>It doesn't render eyes overly large or anime style. More of a stylistic preference, makes outputs more usable in serious concept art.</li><li>Adds back NSFW knowledge. You can generate nipples and pussies with this LoRA. Nuff said.</li><li>Works with quantized versions of Qwen and the 8 step lightning LoRA.</li></ul>If you like my work, please consider supporting me at <a target="_blank" rel="ugc" href="https://ko-fi.com/vestalwater">https://ko-fi.com/vestalwater</a>.<h2 id="comparison">Comparison</h2><img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/4f6b39d4-3baf-4d53-877b-2c9112a89f04/width=525/4f6b39d4-3baf-4d53-877b-2c9112a89f04.jpeg" />A nude woman with large breasts and a blonde ponytail. there is a red vending machine.

In order to make Qwen generate women with flattering proportions, I don't describe any of the women in the dataset to have wide hips, or large breasts. This way you're teaching the lora that woman = image in dataset, not curvy woman with wide hips and large breasts = image in dataset. As a result, the lora learns that a woman by default looks like the image in the dataset.A similar thing is also happening with the way skin and light transition is rendered, you'll note that every single image in the dataset contains concept art style thick brushstrokes. I do not describe this in the captions in any way. As a result, the lora now renders everything with thick brushstrokes, which is what I wanted for this lora.Making the Dataset not look badIllustrious is notorious for generating bad eyes. You either have to hires fix the image to get good eyes, but this results in overly crazy looking hair. So in order to fix it I just ran a facedetailer on the dataset, and this worked wonders for the eyes, as you can see in the sample dataset images. It still isn't perfect, the irises aren't perfectly round for example.Bad hands. This one you can't fix with a post process method reliably (even inpainting is hit or miss), so I just rolled the dice until I got good looking hands.Nonsensical backgrounds. You just roll the dice until you get a background that is semi coherent.If I had more patience, I would've photoshopped the entire dataset for garbled looking text and logos.
