Farfalla di pietra incrinata che brilla dolcemente nel buio

Attention-grabbing dramatic Dark fantasy book cover illustration. A single butterfly suspended in darkness, wings cracked and fractured like stone or obsidian. Fine glowing fissures of dim golden light leak through the cracks in the wings. At the butterfly’s thorax, a small luminous core stone embedded in its body, glowing softly from within. The butterfly appears burdened, heavy, damaged but still intact. Background is deep charcoal to black, filled with subtle ash, smoke, and drifting embers. No scenery, no landscape, no flowers. Lighting is cinematic and high contrast, with the butterfly emerging from shadow. Mood is ominous, tragic, restrained, and unsettling. Style: painterly realism with gothic undertones, dark fantasy aesthetic, cinematic lighting, shallow depth of field, dramatic chiaroscuro. Composition centered, strong silhouette, designed to read clearly at thumbnail size. Emotion conveyed: beauty under unbearable weight, transformation as suffering, power as burden.
