I don't find her very attractive at all but screenshots are at least tolerable. Please don't make her talk. Her voice sounds like a fuckin Goblin whispering casual violence in your ear. How charming.
I love her dominant voice and her hairstyle that gives her personality, many people do too. I think criticism and discussion about the voice of Minthara is primarily important for people who wants to hear this voice throughout the game, and not kill her at the first meeting
