May I point you to one thread I started some time ago to specifically pick up this topic:
There are numerous very sophisticated character modeling tools from various games out there that could be utilised by FD for automatic character model and face creation for NPCs. The best two are those from Black Dessert and Eve: Online, IMHO:
Black Desert:

Eve: Online character creator:

Since we will definitely need character models once the first person add-ons for walking around ships, stations and planets will be released, my bet is that FD is waiting with the release of any visual representation of persons until then to have enough time to do it right - it's a huge amount of work, I guess, so I understand they want to take the time they need to get it right.
