Dark Goblin Shaman in Haunted Swamp

Create a dark fantasy cinematic illustration of a sinister {argument name="creature type" default="goblin shaman-warrior"} crouching low in a haunted swamp at night, centered in a three-quarter view and staring directly at the viewer with a vicious grin. The creature has mottled green-blue leathery skin, a long hooked nose, glowing icy blue eyes, huge pointed ears with small rings and ornaments, sharp jagged teeth, clawed feet, wiry limbs, and a crown of tangled dreadlock-like tendrils rising from its head. Dress it in tattered tribal leather, ragged cloth strips, bone and metal trinkets, and worn dark shoulder armor. Both forearms are encased in oversized ancient gauntlets made of corroded bronze-black metal, each ending in long claw-like prongs and containing one large circular glowing cyan magical core, for a total of two glowing gauntlet cores. Add wisps of turquoise ghost-fire curling around the gauntlets and drifting through the air. The setting is a misty dead marsh with black mud, shallow reflective water, reeds, twisted leafless trees, hanging moss, and jagged thorn-like silhouettes. In the far background place a looming gothic dark citadel with many needle spires and one bright circular blue arcane sigil glowing on its facade. Use a deep midnight blue palette with cyan rim light and magical glow, wet reflective surfaces, heavy fog, high contrast, ultra-detailed creature anatomy, ornate armor texture, grim fairytale horror mood, dramatic low-angle composition, sharp focus on the goblin, cinematic concept art quality, square format.
