off-road truck 3d model

Create a detailed bas-relief sculpture in 3D, front view only, with a flat back surface. The model should show a rugged off-road truck on top of crossed engine pistons, surrounded by laurel leaves. Keep the depth shallow like a wall-mounted plaque, not a full 3D figure. The truck and details should appear carved in relief, with visible texture on the tires, metal, and stone base. The rear side of the model must be completely flat, no details, ready for CNC/laser engraving or molding. Use high contrast detail and sharp edges suitable for manufacturing. Black and white reference style. Maintain proportions and mechanic realism.
