Chelle is a woman with fluffy brunette hair, hazel eyes and pronounced cheekbones. She is not based on a real person.

Version 1.1 for SDXL came out much better than 1.0 for overall quality and especially face quality. Works best at a weighting in the 0.5-0.7 range; at full 1.0 weighting tends to come out overcooked. Most faithful checkpoint seems to be Juggernaut XI, however a lot of images with Jugg XI still have a blue tint/background. "Blue tint" in the negative and/or other colors in the positive usually avoids this. Juggernaut Ragnarok does not seem to have this problem as much but fidelity to the training data is IMO not as good.

Also for the 1.1 XL version, if you don't specify "brunette" you often get a dark-skinned (black) woman.
