The thing I don't like about the Mithra series is that they're all the exact same style just folded onto different Warframes, and of course there's that Heavy Blade skin as well. Now, that's not to say that it doesn't take an incredible amount of work to do that, when different Warframes can have very different body shapes and complex curves and angles between them. While the swirling Chinese-like patterning works for someone like Ash or Titania, it doesn't seem like it gels well with Valkyr. At least, in my opinion.

Of course, whether something "gels" or not with a Warframe is hard to define. Certainly, Valkyr can be elegant while being just as deadly. Some of her other skins and helmets prove that. But this plastic-teacup look with glowy bits doesn't cleanly match with Valkyr, even after the helmet change (visible in the 3D model viewer, but not screenshots yet, it seems). I do think the new helmet is much better, personally.

I'm trying to imagine Valkyr's default helmet, Delusion helmet, and especially ones like Kara mixed with this skin and they can't sync up at all.
