Requests that are overly detailed and really dumb. Like, "lul so randum" stuff. For example, "a vampire with a shotgun that shoots bees, shooting at an orange that's alive, then the orange cries and the vampire falls off a building." Problems with this: 1 you clearly just made it up off the top of your head. This isn't something anyone cares about. 2 you've put in so much detail that the artist cannot be creative with it, not it isn't interesting or fun to draw. 3 it's a really ****ing cringey attempt at seeming like you're not the desperately boring person you are. 4 you're assuming this person is drawing multiple frames, which most people don't do, and nobody would want to with such a shitty prompt.
