I've found this picture on G+, made a search through Google Images to try and find out whence it came to give due credit, but to no avail. I wish I knew if there were other awesome pictures like this one. It's a vaguely East Asian-looking hobgoblin. This looks very inspirational for a Chīmèi (TCE p113).
I especially like the extra detail like the darkness character (闇) on the forehead of the Champion. It could be a spell matrix or something like that.
