If you want to make any mod crazy ass lol, then you have to consider the smaller enviroment objects that you can add on to the bigger objects . Say you have a balcony with a rail as a boarder , you can place the rail abit inwards so you have a small edge around the outside of the balcony OR if you make a two story building , you can construct a fire escape or a ladder that is held at the top by object joints so it moves abit when you climb up it .
The smaller things count my freind , and correct color use is always a benifit .
