This is a simple Tyrande reskin of the Retera Owl Priestess Model, I changed the hair texture and the portrait. You can download the mdx models and hair dds file here:
Tyrande Owl Priestess model | HIVE

To import the model, just remove war3mapImported\ from the dds file import but not the MDX models.

UPDATE: Added a new Tyrande portrait so you can get the voice lines/lip sync from her.
