Unlike the Thoth Conglomerate's suits, which were based on the Newman bio-suit, I wanted to make the Chinese suit look closer to modern day designs. I even included a sun visor that can be flipped over the clear visor instead of the single autopolarizing visor in the Thoth Conglomerate's suits.
This suit is actually a hybrid design. There's a constricting undersuit layer which partially pressurizes the wearer, but not as thoroughly as the Thoth Conglomerate's suit does. The rest of the pressure is supplied from the inflation of the suit, like in modern space suits. Thus, the Chinese space agency in the setting don't have to make the extremely expensive "smart" multi-layered constricting material used in the Thoth Conglomerate's suits, while the simpler constricting material they use for their undersuit layer allows for less suit inflation. This makes the suits less ponderous and movement constricting than modern day suits, although it's not as flexible as the Thoth Conglomerate's suits.
The same simpler, more utilitarian design philosophy I'll also use for the Russian cosmonaut suit designs. I'll try to base those on the modern day Orlan suits. And, yes, that's a ghostly outline of my next pic since I decided to be cheap and bought a low-quality drawing book with thin pages instead of a proper sketchbook.
Like the Thoth Conglomerate's suits the Voster suit design was based on the form-hugging Newman bio-suit. It also has a single autopolarizing visor. Unlike the Thoth Conglomerate's suits, however, the Voster suits are purposely designed to look much more aesthetically pleasing for advertisement purposes.
This does not mean, however, that looks are all it has going for it. Is is every bit as functional as the Thoth Conglomerate's suits. It does tend to be marginally less hardy, but not to a significant degree.
