Somebody tagged the real artist so you guys can vote to expunge since it's been already uploaded but the guy's name on e621 was goat-kun instead of goat-head so I my bad guys heres the real gallery /g/1740689/6740f26684/ Also heres to e621 so you can see where I made my mistakehttps://e621.net/posts?tags=goat-kun
Could be resample, of course - which would explain the colours quite nicely, but in the image 1, linked above, there are two lines over the Rouge's left breast, whereas in the old gallery thouse lines on the corresponding image are abscent.
As for the name difference - artists have several pseudonims some time, it happens ¯_(ツ)_/¯
