I took what you listed in List 1 and made my own design based off it. :3
~Deep purple or red
~Yellow/orange markings
~Feathers
~Warrior-like (no armor though) (I used the scars to portray a warrior spirit. :3)
~Piercings
~Symbol/ancient marking (The lettering on it's side spell out 'Truth' in Cirth, the dwarfish language Tolkien created. I can change what it says, if you want. :3)
