Academic Shoot; Balance

1. I think i followed the rule really well in this one. This wasn't going to be my balance photo but with a second glance I thought it would be better than my original one.
2. The subject in this photo is the dark squares created by the repeated columns.
3. Its not very clear unless you're looking for the rule. I see people thinking that the two gentlemen at the table are the subjects.
4. I think it could make this better by capturing the same photo but without the kids.
