Is is really the tree that is wicked? It looks as if it has been charred and burned... so perhaps wickedness has taken place beside the tree? Perhaps some herbal healers were mistakening burned as witches?! Very thought provoking build! :)
Now that is truly beautiful! Seriously! It reminds me of drawing exercises I used to do. Making trees without lifting the pencil, one continuous line. They always turned out evil looking. Love that you gave it a real presence with the eyes. Perfect for Halloween. Stunning! Literally!
