I'm afraid I'm going to have to politely deny that request. The Four Beasts are for my personal fan fiction, not the fan fiction of others, and I'd prefer they stay that way. Thank you for asking, though.
Could you make a dojutsu image for me? It would be Silver/Gray (think cloud cover) and similar in appearance to your Teiougan and the Tenseigan. The name of the doujutsu would be the Kishōgan or "Weather Eye".
