AI Drawing Prompt Reference

Draw a Sherlock-style hat. Start with a horizontal baseline, then build the brim outline using segments and points. The crown consists of two intersecting ellipses sharing a vertical centerline, tilted at angles. Fill the interior and surroundings with smooth curves and a grid of curved surfaces to create a 3D effect. The overall shape is symmetric, with interwoven curves forming a complex geometric design.
