I should have been clearer. What I mean is a moment like [url=https://youtu.be/y4S0q3xWJyQ?t=40s]this[/url] (:40 to :43). The moment where she actually channels the animal. That blue/purple magic stuff that appears as she imitates the animal.

I could be wrong, but I always saw that as for the benefit of the reader or viewer so we know she's using her abilities. In a text format, you can just describe her channeling the animal's spirit and then performing the resulting actions. No need to describe the spectral animal shape.
