Realistic Wooden Eye Sculpture

I need a finely carved wooden sculpture that captures the intricate form of a human eye. The piece must read as realistically as possible—precise iris detail, subtle eyelid folds, convincing depth in the sclera—rather than an abstract or caricature style. Any hardwood you’re comfortable with is acceptable; just tell me which species you recommend and how its grain will influence the final look.

Please confirm the dimensions you think will balance detail and shipping practicality, and outline your finishing process (sanding, sealing, protective coat). A few progress photos would help us lock in the proportions before the final detailing.

Final deliverable: a sealed, exhibition-ready wooden eye sculpture, safely packaged and shipped to me.
