Hyper-realistic 3D prop rendering, pure dark charcoal gray background without clutter, medium shot fully capturing the subject, side soft lighting, a traditional wooden longbow placed along the diagonal. The main bow body is made of distressed light brown log material, with natural wood grain and tiny usage scratches on the surface. The grip area of the bow is wrapped with dark brown leather straps for anti-slip treatment. Both upper and lower bow tips are light off-white bone reinforced structures, tied with light brown twisted bowstring through dark brown thin ropes. The bottom of the bow body contacts the projection surface and casts a soft faint shadow, highlighting the rough and simple texture of wood, leather and bone, 8K resolution, no extra decorative elements, 1:1 square aspect ratio.
