As the note on the sketch suggests, I realized about half way through drawing this that I was totally channeling Tales from EarthSea, the Ghibli movie based on Ursula K. Le Guin's book series. I really enjoyed the movie and I bought the first book recently and am excited to read it. I really enjoyed The Left Hand of Darkness, one of her Sci-Fi novels. It had a lot to say about social norms/labels and, for me anyway, why they don't matter except to those who seek to oppress.
