Feel free to post any creative medium or style you can dream of.The only firm criteria that will be enforced is that the content must be original art made by you. I am a strong supporter of artistic freedom and I see nothing wrong with taking inspiration from other artists or remixing to create something entirely new. If however the art is not made from scratch it's good etiquette to cite your sources so people can understand exactly what they are curating.
It is important that you cite the original source where you were inspired to create your work.
in this case it is:https://www.artstation.com/artwork/nYgVJ6
