Naathbel - Nature's healing

Environment illustration for my DnD game (homebrew) - Naathbel is a druidic city built around giant trees. It is the sedentary city of an usually nomadic people and very rarely taken care of, overgrown and ruled by nature. The trees grew around a central one, the Mother Tree, which shines with rainbow colors and is the host of the Haran, leader of the druid clan.
