Design a 3D-rendered abstract botanical composition where organic floral forms seamlessly blend with bold geometric patterns, creating a modern and eye-catching artwork suited for large-format murals or posters. The 3D rendering should enhance the depth and texture of the floral elements, making them appear as though they are rising from the surface, while the geometric shapes remain sleek and flat, creating a dynamic contrast between nature and abstraction. The style should combine semi-realistic, 3D-rendered botanical elements with clean, defined lines for the geometric shapes, offering a visually engaging interplay between softness and rigidity. Simulate a wide-angle view to showcase the grandness of the composition, ensuring that the 3D-rendered florals and the geometric shapes remain cohesive in the overall layout. Lighting should remain minimal and flat, characteristic of abstract designs, allowing the 3D-rendered florals to stand out against the bold geometric backdrop. The background will feature simple geometric shapes like circles, triangles, and squares in muted, cool tones such as soft blues and greys, providing a modern, minimal canvas. The foreground should showcase detailed floral clusters, such as lotus flowers, peonies, and magnolias, rendered in 3D with vibrant, warm colors that break through and intertwine with the geometric patterns. In post-production, add slight grain textures to the geometric shapes to soften their appearance, integrating them with the flowing lines of the 3D florals, while minimal color grading ensures the composition feels cohesive and balanced.
