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"
