Which is too bad because it started promisingly, for the first few moments you could buy that it was a transformation, rather than a sort of parasitic explosion from within. A few clever edits could make it more palatable.
To me, tree transformations are best when they work with one of my lesser fetishes: immobilization via transformation. Specifically when the transformation is just severe enough to cover their body and root her in place, but you can tell there's still a human in there. Extra points if the bark also covers her mouth.
Shame there isn't more tree transformations in the vein of that tree girl at the start of Wishmaster:
