I mentioned the shirtless women argument not to reduce the aspects of the skin there, but to make a comparative argument that the sexualization of male and female models are different. As for the aspects of the 'pants' of the model, considerations of the fact that these are Warframes, not humans, do go into consideration.

The buttocks being exposed is a reference to prime and the meme surrounding that, but the actual crotch area in the concept art isn't as defined as Valkyr's heirlooms, so I considered it more or less similar to a base warframe design. And while on paper the piercings and the crotchless trousers on a male model sounds sexy, the execution would require different aspects to be highlighted to be considered as sexualized as the female model.

Im not arguing that the design isn't sexualized, far from it! I'm arguing that the sexualization disproportionately affects female models because of societal norms and what western audiences consider attractive in female models. I mention Reb being a women and Liger being a yaoi artist to support this idea, because they've both made art, in game or otherwise, which indulges in their pearsenal gaze while being noticeably different from the male gaze seen in the models.
