The strangest critique I've recieved was when I offered my comic to be shown in a comic book gallery exhibition but they didn't want it, only reason given was that "it's not good enough, there is just something missing". Another one was when last year I tried to pitch my comic, the first full-lenght story to be specific, to publishers in a comic book pitching event, and while they didn't reject my comic outright and will take a year to decide what pitches to choose if any, they still were like "we're not sure can this comic be published outside your hometown since it's story is inspired by local legends and ghost stories". While that is true, I myself don't see how that would be a problem, it's not required to know these legends before hand or be interested in them, I've just wanted to utilize them in my stories and they aren't always the main focus, most of the things (the characters, the story, the setting) I've completely made up myself.
