the artist deleted their original blog so you'll have to search for reblogs or internet archive it (I didn't save any of it), but their username was fullysketch, which I had to look up. their current username is fullertoons, but they haven't drawn this au on that account.
i'm not really knocking them because before they started drawing the "bad boy au" exclusively I fucking loved their art, with pic related being an example of their "canon" works.
at first I was kind of interested in said Bad Boy AU, because it looked like marco being a badass (did boxing instead of karate) and star being more like moon, basically a proper princess. and they didn't seem to get along
but then the artist decided to go all grimdark up in this shit by combining that with "what if star was sent to st. Olga's," and so the cute, gentle, well-behaved star in those pictures is actually a super tragic brainwash victim who's not "real star"
except all the art of them together was just standard cute scenarios that might as well have just been regular starco. especially since star would sometimes still be drawn as acting like star ("her true self") and marco was still cautious and into Jackie
for whatever reason everything about it rubbed me the wrong way. just the reducing of star and marco to a typical shoujo anime-style pairing, the have-your-cake-and-eat-it-too premise of star being tragically brainwashed but not really seeming to suffer from it in any way, the fact that it was so briefly popular I couldn't search for star art without seeing fanart of it and people praising it over the show, and, especially, that I really liked the artist's style and other star art, and hated that then it became the only thing she'd draw. she'd answer questions about it constantly, made a separate blog for it, it was briefly a huge phenomenon in late 2015 and then seemingly vanished just as quickly for no real reason
i guess i'm not still mad, but i sure was once. blast from the past
