Studies - Yggdrasil

I started this study in December and through the months I've been adding little by little to it.
The original concept in my mind was to draw Yggdrasil, the tree of life. To represent the magical presence of the tree, I tried to make a timeless place, where day and night happen simultaneously. Also, notice the rock debris around the tree and the tiny plant growing through the cracks of the first plane rock, near the knight's feet.
