The keyword here is CONCEPT. We all remember the concept art for female au ra as these badass scaly succubi which you can't find a single trace of in the finished kawaii product. There is a real possibility that the femhroth we get look way more bestial than shown in the picture.
Correct me if I'm wrong but judging by the picture it seems like femhroth is but a small detail in the pic/not the focus of it so what we see may be just a very quick/rough approximation due to the main focus of the picture being on the vehicle and showing off it's mechanical details and she's just there to give us an idea of how big she would be in comparison to the vehicle and where she would be seated.

I think we forget how little the official art often resembles the way races look in game.
Take a look at Elezen. If they weren't wearing the racial gear I don't think I'd be able to ID them as such.
And all the races are given that kind of vague and featureless face. It's too early to get upset.
