Speaking about space ships, I loved the design of Spock's little ship in that one, it was different as well as being aesthetic af! And on that note here's a few ship designs I found rather interesting.
These first ones are more of a fighter type vessels, it'd be interesting to have various models of fighters reflecting the cultures and aesthetics of the various alien species unlike previous ME games where all fighters had the rather same bland design.
IMO during the design process they should think more intensely about the evolutionary/historical background of the species. A lot of sci-fi designs are still based on the basic shape of a bird - a pointy shape with wings on the sides, a good example here:

It does even remind quite a lot of Normandy due to its shape.
But what if some species took their inspiration to flight from creatures with a very different shapes and developed aerodynamically efficient forms from those? Maybe something like this:

Or when thinking about the general proportions of spacecraft, let's consider possible differences between species from high g and low g worlds. Would spaceships from high g worlds be somewhat smaller, more "aerodynamic", with more prominent engines due to the necessity of weight savings during earlier stages of their space travel development, with such a design prevailing even after further advances in technology were made and certain restraints became obsolete in deep space?
What about species that for some reason invented highly efficient energy sources and durable materials way before they decided to develop aircraft? Would their aircraft try to emulate their local wildlife much closer than other species, simply because they could due to available technology right at the start of this thecnological development? A bit like was done in "Oblivion", just maybe with proper wings for atmospheric flight:


ps.: While browsing some sci-fi art a picture came up, that made me think that it would be pretty interesting to visit a large planetary spaceport or a military base with a lot of traffic going on to and from space. Lots of technical personell checking the air-/spacecraft, (un)loading cargo, tall towers and maybe deep vertical tunnels/shafts leading to underground facilities.
Here is the picture:
