abstract face sculpture 3d model

Generate a low-poly 3D model of the three-panel abstract face relief artwork. The front surface should accurately capture the distinct, sculptured, low-relief details and planar forms of the faces with smooth, clean transitions between the raised elements. The sides and back of each panel must be perfectly flat and perpendicular to the front surface, forming clean, rectangular prism shapes with sharp edges. Ensure the model maintains the individual panel separation. Output the raw mesh only, without baked textures or color maps, suitable for further texturing and rendering in SketchUp.
