I like this photo and I chose it because it shows hard work and dedication to a certain task can help get stuff done.
A rule of composition that this photo demonstrates is simplicity and this is shown because the two people shown in the photo are building a structure or a house together.

I chose the photo below because it shows a group of hard working students working on what looks to be a science project.
I believe this demonstrates balance because it looks almost symmetrical with the way everyone is sitting at the table.
