Dark Fantasy Goblin Shaman in Haunted Swamp

Dark fantasy cinematic illustration of a sinister [goblin shaman-warrior] crouching low in a haunted swamp at night, centered in a three-quarter view, staring directly at the viewer with a vicious grin. The creature features mottled green-blue leathery skin, a long hooked nose, glowing icy blue eyes, huge pointed ears adorned with small rings and ornaments, sharp jagged teeth, clawed feet, wiry limbs, and a crown of tangled dreadlock-like tendrils rising from its head. Dressed in tattered tribal leather, ragged cloth strips, bone and metal trinkets, and worn dark shoulder armor. Both forearms are encased in oversized ancient gauntlets of corroded bronze-black metal ending in claw-like prongs, each containing a large circular glowing cyan magical core. Wisps of turquoise ghost-fire curl around the gauntlets and drift through the misty air. Setting is a foggy dead marsh with black mud, shallow reflective water, reeds, twisted leafless trees, hanging moss, and thorny silhouettes. In the far background, a looming gothic dark citadel with needle spires displays a single bright circular blue arcane sigil on its facade. Deep midnight blue palette with cyan rim lighting, wet reflective surfaces, high contrast, grim fairytale horror atmosphere, dramatic low-angle composition, sharp focus.
