Sorry guys I must remember to stop basing my concepts on my perfectly formed body
Seriously though, altering the musclature and even making the bones more visible isn't a big job. The stomach/guts area is sunken not because they've been starved its because they've not been used and atrophied away. The bloated look could be mistaken for overfed and is really only seen in third world contries where disease is more of a factor than proper starvation. If anything looking at pictures of victims of the holocaust and concentration camps will give a more fitting look to them.
The shoulder pads as rank could get quite fun, "I'm a commander and so my shoulder pads should be larger and wider that my subordinates" Imagine 5ft wide pads
If we make is so that this guy has the largest pads and make them smaller that'd work, also what do you guys think about different colouration for each of the ranks. I'm not talking about the burgundy outer layer, that should stay the same so they can be identified as etherals (or whatever we're calling them). The inner layer though could be used to signify the different ranks. In this case if this one is a commander the Khaki mid layer and midnight blue inner garment could change depending on rank. What do you guys think? Obviously it'd be daft to break away from the muted 'burnt' look of the colours to have a bright green or something as that'd break with the dark foboding feel.
Cpl F. Don't worry about the psi amps as that was just a flight of my imagination and not canon in any way. I wanted to give the clothed one a feel that they are imposing and in contrast on the autopsy table, I wanted to give the player the impression that "this puny creature is the one that's responsible for all that trouble?"
