A drawing of a flower with many leaves on it

Create an intricate, geometric mandala that combines floral and abstract patterns, focusing on perfect symmetry and a harmonious design. The mandala should feature interlocking circles, triangles, and petal shapes, radiating from a central point, with at least six distinct layers of increasingly complex patterns towards the edges. Use a medium-weight line, similar to a 3-5 point brush size, to outline each element, ensuring the design is clear and suitable for detailed coloring activities. Although intended for coloring, present a preview with a calming color palette of soft blues, greens, and purples, but keep the design predominantly black and white. Include subtle lotus flowers at key intersections and incorporate spiral patterns that add depth and texture to the background. The final design should be optimized for adult coloring books, with well-defined sections large enough to be filled in with color easily.
