I supposedly have good ' spatial awareness ' , I'll try to explain . In it's simplest form , it is awareness of the the space between objects of focus . For instance , if you were to lay on the ground under a tree with full foliage and look up , most people would focus on the trees' limbs and leaves . Some people , often artists , give the space between the limbs and leaves the same ' weight ' as they do the limbs and leaves . An example of that would be hanging a picture on a wall and ' weighing ' the space around the picture and then visually balancing it . Think about placing a painting between two windows , and ' balancing ' the space on either side of it until it looked right .
Mind you , this is a very basic and simplistic ' Wiki ' explanation of it . Hope it helps
