>>35440399If you want a suggestion, I've found after lots of fiddling that using this at the start of all my Gura prompts significantly increases the quality:
((masterpiece)), best quality, highest quality, line-art, hololive, ((gawr gura)), loli, flat chest, (white hair), blue eyes, beautiful eyes,
And if you're using the leaked NAI model, don't forget the standard negative prompts:
lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry, artist name
