(Image of a complex mandala design suitable for coloring, featuring intricate details and a variety of shapes and patterns.  The design should be high-resolution and suitable for printing.  The color palette should be predominantly black and white line art, suitable for users to add their own colors.  The mandala should be approximately 8 inches in diameter when printed at 300 DPI.  The design should incorporate both geometric and organic elements, with a balance of positive and negative space.  The overall style should be evocative of traditional mandala designs, but with a modern twist.  The level of complexity should be high enough to be engaging for adult colorists, but not so high as to be overwhelming.  Consider incorporating elements such as:

*   A central motif with radiating patterns.
*   A variety of geometric shapes, including circles, squares, triangles, and other polygons.
*   Floral or leaf-like organic elements.
*   Intricate linework and shading.
*   A border that frames the central design.

The image should be provided as a high-resolution digital file, suitable for printing and digital coloring applications.)
