When looking out the windows of Citadel Station, I was mostly impressed that they had flying vehicles in traffic patterns outside. However some of the in-game skins leave a lot to be desired.
Some examples:
This very low resolution picture for the deck (highlighted in red) certainly could improved, couldn't it? The pipe that just ends in space could always be attached to the building too but let's not get too picky. (LOL)
Also the buildings in the background - highlighted here in green - wouldn't suffer at all with an upgrade.
Of course, two versions would have to be made - one for the standard Citadel Station and one for the version where it's under attack (and all the red lights are on)
