I don't think this needs a mature tag at all, whilst she is naked, she is a robot and she doesn't have any visible genitalia, when it comes to how human she looks here, she looks more like a human wearing armour or metallic clothing than a naked human.
On the other hand, I think pic of her in the white costume needs a mature tag due to her camel-toe
I cannot thank you enough for these references! My only qualm is that they are a bit dark (on the black parts, mainly) so some of the details are harder to see in specific angles. However, these are by far the best references out there. Thank you so much for uploading these!!
I wouldn't mind seeing some good reference images on Eva. In early game teasers I thought that that was Miranda with a suit redesign and I was digging it. I was a little disappointed to find out that it wasn't Miranda and that she didn't get a suit redesign not that there is anything wrong with ME 2 Miranda.
