The basic model looks very anatomically correct, especially its pelvis - it shouldn't be like that; the groin and anal area are usually covered with loincloths... I would base the basic model on the "grade" model, but only with "shorts"... and here are some simpler shoulder pads and possibly a helmet...

But in general, I think that such a skeleton has the right to exist as an embodiment of the idea of equality before death.
