body: Is it legal to use someone else's modeling techniques and/or art style?
  
  
  Specifically I'm talking about a popular MMD modeler known as TDA, to create his characters he uses big eyelashes, colorful textures, etc, I create a model of my own using the same techniques, art style and similar proportions but I used those to create my own character, it is not an edit since I made it using blender yet I'm worried because I don't know how copyright works in this situation.
  
  
  A few examples of things that look similar in my model are:
  
  
  * the eyes (I used exactly the same mesh here since the effect it creates adds more depth).
  * the highlights on the eyes (not the same mesh yet same technique of separate materials from the eyes).
  * the ears (placed proportionally exactly at the same place where the tda model ears are, meaning that the distance between the eyes and ears is exactly the same).
  * the textures on the face and body are similar but I painted them using a softer style (the shadows are proportionally in the same place).
  
  
  Everything else from the face to the hair, body and animations is my original character.
  
  
  I can include pictures of both the tda model I'm using as reference and my model if needed.
