green cactus 3d model

Create a highly accurate 3D model of a "White Head Cactus" (Cephalocereus senilis), strictly based on the reference images provided. The cactus must have a tall, columnar cylindrical shape with vertical ribs. Surface covered with dense, long, thin white hair-like spines, giving a soft, fluffy appearance (similar to white fur). The green cactus body should be subtly visible underneath the white hair in some areas. Maintain natural irregularity — the hair is not perfectly uniform and may vary slightly in length and density. Top of the cactus slightly rounded. No flowers or fruits unless shown in reference. Texture must be realistic with high detail: fibrous hair strands, soft shading, and natural variation. Base slightly darker and denser. Style: realistic botanical model (not stylized, not cartoon). Lighting neutral studio. Output as clean 3D mesh suitable for visualization (and optionally 3D printing), with correct proportions and no deformation.Ensure the silhouette matches the reference exactly. Do
