Focal point is in the middle and the weight is the same on both sides. The cups, people, and background are all weighted equally on both sides.
Focal point is on the right and most of the weight is on the right side. There is only one character on the right side and the building is leaned more to the right.
This image is balanced all of the weight is evenly distributed throughout and the focal point is in the middle. I used a circle for my shape because when the formation is split down the middle you have the same amount of characters on both sides, thus making the image balanced.
