Hahahaha, "boobs too big" is the weirdest critique you've ever received? Hoo boy, my weird critiques go way weirder than that...
"Why does your story have so many girls in it? I don't think it's bad, I just don't understand why there are so many." (note: There were three female characters in this story... and three male).
"Oh... you want to make Fantasy in a modern setting? Haha, that's cute... but overdone. I think you should make something with like... steam powered zeppelins, that's what I'm into right now." (wow, yeah making things steampunk immediately makes them original, what good advice. ).
"I thought this character called Lyn was a boy. She's very boyish... not that there's anything wrong with that, I guess... but I thought she was a boy, so I think she should be more feminine with bigger boobs and maybe eyelashes...?" (note: The character's gender was in no way relevent to the story of this short comic).
"Your comic is bad."
Me: "Okay, well, nobody's forcing you to read it."
"NO. I will continue to read it, because it's very interesting that it has more readers than mine... even though my comic's art and story are better. I am reading in an attempt to understand why people like your comic..."
(I think this is one of the funniest. Just... WOW.)
