Made some more quality of life tweaks to the skin, darkening parts of the helmet to better match the tone of the body, as well as improving the clamps on the helmet.

Added metal parts between the chest and shoulders, darkened parts above the chest, and removed the metalness of the APEX markings; also moved the markings from the 4th tint to the 1st tint (the gray of the body). I will update the preview images soon.
