Blackwork tattoo design for a full back piece

Blackwork tattoo design for a full back piece. A tree rendered as mostly root system: dense, tangled, asymmetrical dark roots occupying the lower half, forking and crossing, some thick and ropey, some thread-fine, a few broken and ending abruptly, emerging from shadow with no drawn ground line. Roots braid upward and converge into a single narrow trunk at the mid-back with open negative space around it. Above, sparse bare branches spread outward across the shoulder blades — minimal leaves, lots of visible skin, open and unfinished at the top. Fine linework and stippling texture, no solid fill, no colour, no outline border, edges fading softly. Vertical composition on a human back, trunk aligned to the spine, roots weighted heavier than the canopy. Organic and irregular, hand-drawn, high contrast between dense base and airy crown.
