Hi there. First of all this is a great illustration. Secondly I just started writing a story and I'm googling words to make sure the concepts I'm using don't already exist and violate a trademark. I'm creating a character type called a Psy-Night. When I googled Psy-Knight your image came up. Your Psy-Knight looks really cool, the design of the knight and horse is so cool looking. My concept is visually different, it looks more like a cross between a Spartan from Halo and an Alien's exoskeleton. Hopefully it's cool with you if I use this term even though you've already coined the term. I can always use a variation of the word if your not cool with this. Cheers.
