Picked a short parody to do a small test on variant set art. The penis in all 3 pictures are exactly the same. If I use AI to decensor on these three pictures separately, the penis will be slightly different, affecting the consistency of the art. Thus, I only removed the bar-censor in pic 1, then used MS painting to crop corresponding penis and paste it into pic 2 and 3, and do some manual & AI fine-tuning in the end.
Overall, you can only barely see the traces of collage in pic 2 & 3, and the overall quality is fine/not so bad level. If you can use Photoshop or other professional tools, maybe you can get a better results.
4/26: Found out some strange liquid on penis is not made by abubu and make the pic looks bad,erase the liquid to improve the overall quality.
