Realistic 3D Portrait for stone machining

I need a faithful, realistic 3D likeness of one person for 3D printing. The final piece will be a head-and-shoulders bust, the mesh must be clean, watertight, and manifold. I have a few good photos—and can supply them the moment we start. If you discover you need an extra angle, just say so early in the process.

You may sculpt in Blender. Fine pore and wrinkle detail is welcome, but please keep proportions true to life and avoid stylization. I plan make a real size 3D stone statue.

Deliverables
• High-resolution working file (.Blend)
• Decimated, watertight STL/OBJ ready for SLA/FDM printing

Acceptance criteria
• Strong visual match to the reference photos
• No non-manifold edges, self-intersections, or inverted normals
• Scales cleanly to the stated print height without loss of surface detail

When you reply, include examples of previous realistic portrait sculpts so I can gauge fit. I’m ready to get started as soon as I find the right artist.
