Design the composition for a large, elegant, mystical dark-fantasy back tattoo. Leave approximately 20–30% of the skin visible, distributed naturally. The night sky occupies the upper third, extending from the top of the trapezius muscles down to the thoracolumbar junction. A female figure takes up almost the entire right half of the back. The owl, full moon, and open grimoire are clustered higher up on the left side. The lower-left quarter is reserved primarily for fading smoke and a fragmentary scene to be added later. The composition is balanced, vertical, and airy, avoiding a solid "wall of ink" effect.
