• Link to another artist who made the same thing, just better.
  
• Here is a tutorial by another person who made the same.
  

This is clearly made by following a tutorial (likely the one I just shared) and therefore it's not "made by you" but "copied by you". The colors and layout are copied directly without as much a nod to the artist who inspired you to try and directly copy their work. On top of that, you did a bad job as one can see around thedark purple outline which is cut awkwardly because the shape it is tied to is placed awkwardly without any clean up done it. (It is also most likely made in Photoshop and not Illustrator.)
