Dark Romantic Jungle Letter Scene

Create a cinematic dark Romanticism jungle scene in a wide 16:9 canvas. Show a lone small human figure, {argument name="traveler description" default="a man in a dark coat seen from behind"}, standing near the lower left foreground on a muddy forest path beside shallow water, facing into an immense dense rainforest. The environment should feel like an overgrown mythic cathedral: towering tropical trees, vines, palms, tangled roots, wet leaves, mist, distant cliffs or ruined stone forms, and a pale waterfall or river receding into the center depth. Use dramatic chiaroscuro lighting with shafts of warm golden light cutting through deep green-black shadows, humid haze, and painterly detail. Integrate a huge translucent typographic form, {argument name="giant letter" default="D"}, rising in the left-center background like a monumental glass letter filled with forest silhouettes. Add a single opaque dark olive square block near the upper center-right, floating over the foliage like a minimal graphic overlay. Include delicate thin gold ornamental vertical lines along the far left border and subtle distressed texture, giving the image an antique book-cover or literary essay thumbnail feeling. Color palette: {argument name="color palette" default="black, deep jungle green, muted gold, smoky beige, and copper-orange leaves"}. Mood: {argument name="mood" default="ominous, sublime, romantic, humid, and mysterious"}. No readable text, no logos, no modern buildings, no extra people.
