A lone necron_deathmark is depicted in a close upper-body side view, adjusting into a firing posture while the long rifle and its optic assembly dominate the foreground. He keeps both hands correctly placed on the weapon, with the rear hand wrapped around the grip and the support hand beneath the fore-end, the buttstock pulled into the shoulder as his single eye aligns along the weapon. Focus on the machine precision of the hands, the skeletal arm structure, the weathered metal textures, and the distinctive cyclopean face with one central glowing green eye. The scene is set inside a dim necropolis chamber with dark stone, green energy lines, and a softly blurred background. necron_deathmark, necron, cyclops, one_eye, glowing_eye, upper_body, close_up, from_side, synaptic_disintegrator, sniper_rifle, weapon_focus, aiming, two_handed_weapon_hold, shouldered_weapon, indoors, necropolis, green_lighting, dark_background, weathered_metal, skeletal_robot, mechanical_hands
