I have used lots of different approaches in my two assignments to develop compositions that I hope are successful. I have included notes on these separately, but here are a few other examples of compositional devices in my images:
The rule of thirds is always a good basic starting point. It helps to organize this image, and could be used to structure a crop that would add more impact. The framing of an image and the viewpoint chosen are integral to any composition.
A portrait from the same session that uses the rule of space to compose the image.
Some recent images from the city that use juxtaposition...
And two other images that make use of very obvious triangles!
