Indeed, I have. Being a nature shaman, practices such as these are sometimes more useful and practical than colors. However, I hardly use the animals to replace the chakra pools. I use a bit more blunt way:
Base of the totem: a bear. It represents stability and structure, strength to overcome staggering over things in life.
Next level: A rabbit. It represents the ability to be free and to be wise enough to avoid problems before they start.
Next: an eagle. This part represents clarity of mind, the ability to keep a calm mind in situations, and to focus on the prey, not the horizon.
Final: this is a bit more personal, and slightly unorthodox compared to most shaman practices, a wraith. It represents the ability for your spirit to be strong, and attack the challenges that first attacked it.
Hope this helps.
