Create a captivating 3-flower composition, each flower crafted from a unique combination of car parts. The first flower’s petals should be made from pistons, stacked in a layered formation to create a radial effect, with the center featuring a large, worn-out wheel gear. The second flower’s petals can be constructed from brake discs, with their smooth, circular forms radiating out from the center, while smaller gears and bolts form the intricate details. The third flower should have petals made from a mix of curved metal plates and car fenders, welded together in a flowing, graceful shape, and the center can feature a large, rusty engine part. The stems of all three flowers should be made from metal rods, twisted together with brake lines and exhaust pipes for texture, forming a natural, intertwined look. The background should be minimalistic, allowing the metallic shine and rusted textures of the car parts to stand out, with the color scheme balancing silvers, blacks, and rust tones.
