This is a fantastic model, and I think it's my favourite interpretation of a female Tauren to date, especially considering the in-game textures!
That said, the biggest flaw here are the animations. "Draenei" just doesn't make sense for a Tauren, they're far too quick and agile. Something heavier would have been better in my opinion. And another point of criticism I felt is pertinent is that she is too thin. Especially compared to the in-game Tauren, she just looks tiny.
