I made a graphics-art reference for Andrew. I should be working on Cecilia's soon enough. I think I'm trying to catch up on all of my reference pictures, since I haven't done them too often.
Anyways, the bandana is new, and you can see that it's replaced the bracket-shaped necklace that he once had. Now it's part of the sash that carries the Red Eclipse, as some sort of buckle or lock.
By the way, the sketch for this picture is now displayed on my physics binder. People nearby stare at it whenever I have it out on display, haha.
