Cage The Dragon - Final Tutorial Result (picture)

This entry is the result of my first real tutorial "The Taming of the Dragon / To Build A Cage"

UPDATE:
As I'm still a bit learning about the possibilities of dA finally the following versions are available:

• The (now preferred) direct PDF submission here
• The old sta.sh version To Cage The Dragon

Please have also a look to my journal at this link.

One note regarding the calculation: 
On my Laptop from 2010 with a first-generation i7 4 core/HT mobile CPU the calculation of the picture (2400x1800) did need about 20-25 minutes minutes.
So that tutorial should be something what can be cone by the most people (I hope).
Without relection it is even about 1/3 less.

Used Mandelbulb3D v189 [MengerIFS, Quadrat3D]

Discussion (if anyone should want to talk about details ) should be done within the Journal entry.
