A fierce Viking warrior, mid-swing with a double-bladed battle axe, dynamic pose, full-body shot, photorealistic, cinematic lighting. He has long, wild brown hair and a thick beard, a powerful, muscular physique, wearing intricate leather and metal armor with fur accents. His face is contorted in a primal scream, veins bulging, with subtle blood splatters. The background is a misty, overcast mountain landscape with soft, diffused light. The atmosphere is intense and dramatic, with a cool color palette of greys, browns, and muted greens. Subtle glowing particles or embers float in the air, adding to the gritty, fantasy feel. Strong sense of motion and raw power.
