I studied the form of this flower for days before I began drawing. The challenge with this maze was to show perspective and three dimensional shape. The stamens and stigma stand above the plane of the petals and I had to show that with only a few penstrokes. I practiced many different styles, before settling on this technique. The key to this effect was reversing the direction of the curvature of the paths on the stamens and the angle of the switch-backs in the stigma. I'm very pleased with the result.
The two solutions to this maze wander through the petals up into the stamens and stigma. Or maybe they don't, there's only one way to tell and that's your job.
