This is something I just noticed while working in the Foundry, since in the game you never manage to get close enough to really look at the Cardassians closely. Basically, the Commander (Gul) and Captain (Legate) models look ridiculously bloated.
It doesn't seem believable that anyone would actually wear armor that bulky, and it's not true to what we saw of them in DS9. If anything the Ensigns (Gil) look closest to what we saw on screen. Glin doesn't look too bulky, but I'm not sure why part of their uniform is white.
After that the armor just looks extremely oversized and stupid looking.
