Dark Goblin Shaman in Haunted Swamp

Create a dark fantasy film-quality illustration depicting an evil {argument name="creature type" default="Goblin Shaman Warrior"} Crouching low in the haunted swamp at night. The scene is a three-quarter view, with the creature centered, staring directly at the viewer with a menacing grin. The creature possesses mottled blue-green leather skin, a long, curved nose, eyes that glow with an icy blue light, large, pointed ears adorned with small rings and decorations, sharp, jagged teeth, claw-like feet, lean limbs, and a tuft of tangled, dreadlock-like tentacles atop its head. It is dressed in tattered tribal leather, ragged strips of cloth, bone and metal ornaments, and worn, dark shoulder armor. Its forearms are encased in oversized ancient gauntlets made of corroded bronze-black metal, each gauntlet ending in long, claw-like spikes and containing a large, circular, glowing cyan magical core—two glowing gauntlet cores in total. Turquoise will-o'-the-wisps swirl around the gauntlets, drifting through the air. The background is set in a desolate, misty swamp, the ground black and muddy, with reflections in the shallow water, where reeds, twisted leafless trees, hanging moss, and jagged thorn outlines grow. In the distance, a sinister Gothic castle stands, its many spires gleaming, a bright, circular blue arcane symbol glowing on its exterior wall. The composition employs a deep midnight blue tone, paired with cyan rim lighting and magical effects, presenting a wet, reflective surface, dense fog, high contrast, ultra-detailed biological anatomy, ornate armor textures, a somber fairytale horror atmosphere, and a dramatic low-angle composition. The focus is clearly on the goblins, achieving cinematic concept art quality in a square frame.
