I think there should be animals, And NPCs, An example of an NPC could be a shop NPC. It would be a little animation in the corner of your screen when you bring up the shop menu, Like in spore almost. He might say things to you when you buy stuff, He might give you advice, He could tell you about the stuff happening in that sector, Etc.
Planets should have animals, Sheep, Pigs, Etc, However, Different planets could have alien life. As they already have alien plants, Also, Trees are in the game, But they seem to be rather rare, This should be fixed.
You should also be able to hire NPCs as crew members, Who can repair your ship, Who can fight in your weapon's computer, Who can salvage for you, Etc. They should also level up depending on what they are doing, Possibly allowing you to adjust their perks upon level up, Like you can with your character in Skyrim.
