Un gardien mi-pierre offre un galet de rivière dans un portrait en studio

Studio portrait photograph of a practical creature-effects character, a fictional folk boundary guardian deity whose body is half turned to weathered grey stone, the stone spreading from its left shoulder across its chest and face, patches of green moss and lichen in the cracks, smears of bright vermilion powder on its stone forehead. The living half has grey wrinkled skin and one sunken watchful eye. It holds a small round river stone in an open palm, offering it forward. Plain grey seamless backdrop, one large soft key light from front-left, gentle cool fill, three colors only: stone grey, vermilion, moss green. Medium format, 90mm lens, f/8, whole figure sharp, realistic stone and skin texture, practical prosthetics, no CGI look, no glow, no text.
