Recommended settings:

Steps: 30-40

Scale: 4-6 Sampler: Euler a OR DPM++ 2M

The recommended resolution is 1024x1496 , but 832x1216 is completely fine (including reversed into landscape or slight variations). You will see a composition and fidelity difference between the two - depending on your goals, you might want to try both.

Illustrious models (due to their strong prompt following) respond better to negative tags compared to what you might be used to with Pony models. Examples of potentially useful negative tags you can try:

anatomical nonsense, artistic error, bad anatomy, bad arm, bad aspect ratio, bad ass, bad face, bad feet, bad hands, bad knees, bad leg, bad neck, bad perspective, bad proportions, bad reflection, bad vulva, different reflection, extra arms, extra digits, extra eyes, extra faces, extra legs, extra pupils, fewer digits, oversized limbs, wrong foot, wrong hand

Try to tailor what negative tags you use to your specific needs rather than always including them all. A trimmed down version that's suitable for general use is:

anatomical nonsense, artistic error, bad anatomy

These should be used in tandem with staple negative tags such as:

worst quality, bad quality, low quality, lowres

On the flip side, recommended positive tags are:

incredibly absurdres, highres, masterpiece, newest

But do note that certain art styles benefit from omitting masterpiece and newest .

These tags heavily lean into the refined and modern digital look, if you want to generate watercolor these might work against you. Likewise, if you're going for a retro look, avoid newest .

For a traditional art style you might want to include tags such as:

traditional media, painterly, good quality, average quality

Some tags that are useful for steering away from the default anime look include:

POS: painterly, no lineart, blending

NEG: flat color, high contrast, anime coloring, limited palette, outline, ligne claire, lineart, oekaki, jaggy lines, dithering, pixel art, monochrome, greyscale, sketch, anime screenshot
