Rules of Thirds

1. Not that well, but it stills gives a faint feeling of Rules of Thirds. 

2. Choir setup.

3. No, not unless you knew they were a part of the choir, but it mostly looks like they're just helping out moving things. 

4. The people in the foreground kind of ruin the image, I should've tried doing the shot from a different angle where the girls weren't there.
