The Legend of The Bear and The Fox - The Soul

Myth becomes Legend!
This is my take on Koshchei The Deathless or Koshchei The Immortal as he's also known. He is called the Soul because he keeps his soul hidden in a pin, which is hidden within an egg, which is hidden within a duck, which is hidden within a hare, which is hidden within a treasure chest, which is buried under a tree, which is planted in an island.
I recorded the whole process in Procreate.
Thanks again to Ambroise for the suggestion.
