while I think that the spaceman's armour has been nicely upscaled, and refined (with nice colour too), I don't think that the black body sock areas are working. Without shaded detail, they look like black voids, or holes that all light disappears into. I think they need some highlights, just to give it the appearance of rounded, volumnous muscles, rather than a flat, 2D area.
The robes are looking fantastic. I especially like how you've managed to work in that center 'collar-connected-to-rib-belt' thing that was part of the original model (that couldn't have been easy). The layered clothing (jackets, vests, shirts) is working well, and looking natural (just the right amount of shading along the edges).
