Yellow Brick Road

My entry for *heavenriver's UF Challenge Redux Vol. 14:

Black and White

March's challenge will be a Style challenge - its title being Black and White!

This month's challenge will focus on creating beautiful, well-structured fractals without any hint of colour. All fractals entering this challenge must be completely grayscale, no exceptions! This will be a chance for every fractalist to focus on exploring fractal shapes and giving proper depth and lighting to the artwork.
