There's always something that we don't like about the art we make. Whether it be a literary work, or an art piece, there are always in-perfections that only we see. Rant here about how you TRULY feel about your work and just how much it sucks. If you can't think of anything being wrong, remember in art, there's no such thing as perfect. Try to think critically about your work and see things from the viewers perspective. Even the best artists/writers find flaws they seek to improve. Bonus, if you can say how you can improve your work.
