I dunno, looks like the ankles should have good range of motion. If it's enough to be able to plant both feet flat on the surface, I think it'll be at least acceptable at standing poses.
The design is dope, but the HG kit is gonna be absolute sticker hell. Or they might just abandon the idea of color accuracy without paints entirely. Those dabs of yellow all over the place, the trim on the torso, pretty much all of the head that isn't red or white.
I would think it'd make it more likely that you're discovered when you turn your star into a black ball with a gigantic IR signature where a star should be. Any civilization with a cursory understanding of gravity and stellar spectra would turn every telescope they have on you.
