Super detailing stuff involves more than adding doodads to an object. Greebles should have some kind of logical sense behind them, like they belong on the spaceship or scene. Wires should go places, there should be rivets or bolts or plates of some kind. Anything that makes sense. If you have trouble figuring out what to add, look at reference images of various industrial machinery (i.e. rail road equipment from the 1920 - 70's, industrial yard trucks, heavy mining machines, etc...). But remember to add a sci-fi twist to it.
This will give you a good starting point, and, depending on the look you're trying to get, can give you stuff you don't actually have to modify very much.
Try it for yourself and you might be surprised by the results! =)
Still working on Adamant, hoping to get her space-worthy in a few weeks.
Have a great weekend, everyone!
