Wow! The idea of this is amazing! A creature that is clearly not an angel, yet not a demon. I can feel the sadness that they feel. It's like it's saying that they can't believe that it happened, and they regret that it did happen. It almost seems like they want to end their own life, and yet they can't. I can understand this kind of sadness very well, because I feel that sadness myself.
Thanks for your comment. And exactly, he's a hybrid half angel, half demon. His soul not yet is defined. The sadness is something that I wanted to form with great intensity in the atmosphere and in himself as a mode of representation the pain that he feels in his interior.
