Rusty maintenance robot cleaning its leg in a scrapyard

A small rusty maintenance robot sitting on a vast scrapyard, carefully cleaning its own metal leg with an abrasive cleaning pad, one half of the leg still covered in thick orange-brown rust and grime while the cleaned section gleams with bright polished steel, tiny sparks and metallic dust around the abrasive pad, worn industrial design, exposed gears and cables, expressive but subtle mechanical character, piles of discarded machinery and twisted metal in the background, cinematic atmosphere, dramatic volumetric lighting, shallow depth of field, highly detailed weathered textures, realistic metal reflections, photorealistic, cinematic composition, slightly melancholic yet hopeful mood, 35mm lens, ultra-detailed, high contrast --ar 16:9 --stylize 300
