On my Society6 store, in the past I created a horizontal art print of the Oni demon with quoted Musashi philosophy at the side on things related to the martial arts and swordsmanship. And recently, a vertical version has been uploaded to fit in the poster template size on the store as the image was rebuilt on Photoshop seen below. So for those who prefer it vertical as an art print or poster, it can be found on my Society6 page.
I decided to keep the text centered like a box, in the form of zen, so as to not overwhelm the demon below as a subdued dynamic and composition. Whereas, the horizontal version shows more of the demon in larger size.
