I absolutely adore this effort y'all are putting into this. The armor designs alone are worth getting interested in whatever you people are cooking up. The original standard incarnations of MJOLNIR worn by the Master Chief are some of the most simple and iconic armor sets worn in any property. Much of what we see nowadays in Halo looks like it could be in anything from Call of Duty to Unreal, but early Halo stuck to its own design language and I appreciate that you're sticking to that. Your team's rendition of Mark IV as a final transitional model to Mark V is totally evident in the individual pieces to the unique curvature. I can also see a bit of Mark VI in there as well, whether that was intentional or not, and it still looks amazing. Whether bare or adorned with pouches this rendition of Mark IV truly looks like it should have a place in canon.

I do have a bit of a concern though. The unique female builds for Spartans in every game since Reach have gotten progressively worse. From what was reasonable in Reach with Kat and FemSix became rather absurd in Halo 4 and Halo 5. I can't say that I'd imagine most female Spartans having such a petite build to them. Additionally, armor sets for women are no longer form-fitting like they are on male models. They look way too bulky and seem like they would restrict movement to a great degree.

It's obvious that they downscaled female armor models, at least in Halo 4/5, from the male models with little concern for our unique physiology or even generally pleasing aesthetics. One legacy set in Halo 5 actually breaks that trend and it's Mark IV, coincidentally. Seems like we could be a little bulked up. Our curvature is often a little too pronounced and I see that to a degree with these representations you've created. Luckily your rendition of Mark IV itself looks less like an adaptation for women and more akin to a uniquely crafted armor set, stemming from a general design concept as it would with men.
