It's mostly unshaded and in black and white because I was up against an impending deadline, so this was really last-minute stuff. My method of colouring everything and then applying a greyscale filter is probably not the most efficient (or sensible) way to do black and white, though.
Tournaments often feature NPCs (Non-Playable Characters, like in videogames) your characters are encouraged to interact with. There were three Steel Nation officials the Doctors could have interacted with in this audition, and I went with Dr. Alba Bird as she was my favourite. Unfortunately, my meagre talents meant that she spent most of my pages looking like an androgynous man-woman, but I like to think that I eventually improved at drawing her.
