I saw your thread on the NeonMobsters FB group … the other artists are correct: classic characters are typically ok as long as it is your conceptualization of the character and not based on copyrighted franchises from major studios, etc. (i.e. Disney’s visions of the Little Mermaid or Pocahontas or similar).
Go ahead and submit your idea and if their are any issues we can resolve them during our series review process.
