Exercise: Fitting the frame to the subject

For this exercise I have chosen a truck that collects items destined to be recycled.

I start with taking a first shot as a baseline.

Then I try to make the subject fit the frame as tightly as possible. It's not possible for me to shoot right in front of it as a pole is preventing me from it. I fit the frame with the lowest angle possible available to me at this moment.

Now I'm photographing a part of the truck with none of the edges in view.

Now for my last shot I shoot the truck as part of the surroundings, taking about a quarter of the frame.
