I see that someone added a metadata request. Unfortunately, I lost it a long while ago. But at least I remember one thing about this art. I used dark gradient (black and some white) in img2img with denoise strength= 1. For SFW art gradient use in img2img works pretty well and sometimes can show results like this one.
Good god this is quality I made an account just to ask you what Ti's/LoRA's you used? I tried replicating it using the Zankuro LoRA and the Toga TI, but yours has such great quality I feel I must be missing something. Please give me any advice to improve my prompts because from what I can tell nobody does it better than you here.
