Use CFG 5 for perfect saturation/sharpening IMO

Try "worst quality, low quality, lowres, blurry, pixelated, jpeg artifacts, oversaturated, watermark, signature, unfinished, sketch" negative tags sometimes having less can result in better images or even "worst quality, low quality, lowres, blurry, pixelated, jpeg artifacts, mosaic blur, watermark, signature, unfinished, sketch, bad hands, distorted eyes, bad fingers"

Now trying “worst quality, low quality, lowres, jpeg artifacts, cutoff, grainy, distorted, watermark, error, unfinished, sketch, draft, deformed, poorly drawn face, poorly drawn eyes, poorly drawn hands, fused fingers, bad hands, deformed hands, bad fingers, distorted eyes, censored, mosaic censoring, futanari, monochrome” you can remove futanari if you like it

Or even just "worst quality, low quality, lowres, bad, error" and even better "worst quality, bad quality" can be better as too much negative tags can confuse the ai
