vine tunnel 3d model

A dense, thorny briar patch formed from intertwined bramble vines and raspberry canes. Thick, looping vines with sharp thorns weave tightly together around the perimeter, creating a natural barrier. The growth forms an irregular circular patch with a clearly defined open space in the center. The central area is empty, flat soil with no vegetation, trampled and compacted. Vines arch inward from the edges but do not fully close the opening. Thorns are prominent, sharp, and unevenly spaced, clearly visible along stems and tendrils. Leaves are clustered and slightly wilted, with a mix of healthy green and dry brown tones. Fallen canes and broken vines lie tangled at the base of the barrier. Subtle variation in vine thickness and density creates natural weak points in the perimeter. Ground outside the patch is uneven soil with scattered leaf litter; ground inside is comparatively smooth and bare. Organic asymmetry, readable silhouette from above and mid-distance. Neutral lighting, no people, no animals, no text. H
