Create a highly detailed, realistic illustration of a close- up of an orc barbarian Goliath with a sword, in the style of Horde 3D. Incorporate intricate, elegant details with volumetric lighting and scenery, similar to a Twitch streamer's full- HQ render or a Pinterest wallpaper splash art. Use Unreal Engine 4. 2 for rendering, and maintain sharp focus throughout the image. Ensure the digital painting is highly detailed and suitable for ArtStation or a concept art piece by Ruan Jia or Steve McCurry
