Here are some suggestions:

  1. Don’t say it was “100%” made by you when the background is not, it was posted above on a pen!
  2. When creating your first sold script, do not price it this high! 10 euros might not seem like a lot for you! But for others, it may be a lot!
  3. Compare your scripts to others! Make sure something is special about your, otherwise why would someone want to buy it?
