Photorealistic 3D render, 1:1 square aspect ratio, medium shot, front-side eye-level view, solid dark black studio background, a weathered steampunk aerial airship floating in mid-air. The oval copper gas envelope has an aged patinated reddish-copper texture, reinforced with brass rivets and crossed thick ropes. A small brass spire decorates the top of the envelope, and a brass chimney stands on its upper right, releasing curling white steam. The envelope is connected to the gondola below via thick hemp ropes and brass metal supports. The gondola is made of dark brown solid wood, edge-reinforced with brass rivets. An arched warm-lit wooden door is located at the front of the gondola, and multiple round portholes with brass frames are set beside the door and on the cabin walls, with warm yellow light seeping through the windows. Four sets of brass three-bladed propellers are symmetrically mounted on the outer sides of the gondola, and a lit vintage brass kerosene lantern hangs on the gunwale of the gondola. Warm side soft lighting highlights the oxidized metal texture and wood grain, with a soft faint shadow of the airship on the bottom of the background.
