I thought that this photo told the most story. Just by looking at it I can see it all. I can see the two boys helping with a team, perhaps, and building a house. I can see all of the other people running around with nail guns, planks of wood, and blueprints.

This one, definitely showed the most emotion. Maybe they are praying for a loved one who passed or maybe just praying for the heck of it. The lighting of the photo adds to the effect entirely. It sort of gives a happy and emotional vibe. 

This photo knows how to fill a screen. Its very clear what the students are doing and also how enthusiastic they are about it. From border to border this photo is filled with dried ice or compelled students.
