Replace “pure white studio background” with “deep charcoal-black studio background,” change “soft controlled studio lighting” to “dramatic low-key side lighting with deep shadows,” and replace “vivid emerald moss and small patches of pale lichen” with “dark crimson moss, black lichen, and faint wet highlights.” Keep “crisp realistic shadow beneath” if you still want a product-style presentation.

Change “partially wrapped with vivid emerald moss and small patches of pale lichen” to “densely engulfed in vivid emerald moss, thick moss cushions covering most surfaces, and abundant pale lichen,” and replace “lighting highlighting wood grain and moss fibers” with “lighting prioritizing moss fibers, lichen growth, and dewy surface detail.” Add “wood grain visible only through small exposed gaps” to shift visual priority without losing the heart’s root-like construction.

Keep the fixed phrases “product-style studio framing,” “pure white studio background,” “crisp realistic shadow beneath,” “soft controlled studio lighting,” and “ultra-detailed 8K” unchanged. Replace “anatomical heart” with a repeatable specimen subject such as “anatomical human lung,” “human brain,” or “rib cage,” while retaining “sculpted from weathered walnut-colored wood roots and branching veins” and varying only the plant treatment, such as “wrapped with vivid emerald moss and pale lichen” or “threaded with small fern fronds.”
