Bah. Originality "screamers." Just hit "ignore." And it will all fall awaaaaaay... XD When people hate, they tend to be feeling particularly insecure, envious, angry, or frightened--but they don't actually dislike your work. All negative and -wiggles hands expressively- all charged up with everything "bad." When people don't like something, they can just "X" out of it, or calmly state that it does not agree with their tastes. If they go out of their way to create a dramatic scene, they're just waaaaay too unhappy about themselves or their lives, not what you draw/paint/sketch/write/carve from some alternate reality in your mind.

And to the worrying about what others think: Nothing you do can be crappy, so don't worry! As long as you like it, no one else can complain. If they do, you can draw them getting eaten by dinosaurs and/or giant cats--no reply comments, just beautiful art like that. Then everyone is happy. :3
