I don't receive many complains that I could call weird, most of the time is critiques over small things that usually are even just minusculous even on the same critique but except for one that I've received some time ago
It was literally what happened to darthmongoose
It happened with a female character of mine as well who is not very femenine either, funny thing tho, the Critique about the Story was supposed to be about the story, but that lasted almost... two lines? Then there was a long pharagraph narrating from the experiences of the person detecting trap characters in anime, about how naturally "people label characters and need to categorize them properly", or well, very rodundant and almost beating around the bush, oh wait, according to them I was getting this completely wrong
To this day I don't get much what they meant by the critique, except that after an agitated exchange they claimed "Oh no, I just wanted to say that your character was confusing" or that "I was just letting you know in case you didn't realize it" but to me it felt that they tried to be very carefully probably to avoid problems, to tell me to draw bigger breasts or curvy bodies.
Another weird critique that I had was of some random dude on Webtoon Spanish complaining over Scarlet Society, about how crappy as a story it was, that he could do such a better story and that I shouldn't waste my time with it, that my art was so much better for such a horrible story and the guy was like that for at least 5 episodes and really started to annoy me. He went about how he could write such a better story with just his feet and a lot of ridiculous babbling. Even, this guy was so inept that he didn't catch that some of the characters of Scarlet were homages to already existing characters of shows that the author, the previous artist and I like, same for other references that I did but according to him "the author doesn't know how to create characters and so she steals them" which is totally wrong, since ever since I took over I've modified the original designs to make them look more unique and different from one another (And it literally shows from chapter 4 to chapter 7, not a big gap)
I literally told him that I'm an artist for hire, and if he has the cash I can draw his story after all I don't say no to long term paid gigs, but if he only knows how to complain but doesn't show a portfolio or anything of the like is the same as bluffing, that if he was so jealous that no artist partnered with him was probably because his story wasn't that great or his personality was really scaring people away. Still waiting for the famous script that I MISSED 

Tho, he admitted being jealous lmao but then proceeded to call me ignorant and that I would regret it eventually
