Composition

This is bad composition because the composition is "in jail." The black poll is directly in the center of the page therefore the background isn't immediately activated

This is an example of good composition because the first thing you notice is the squirrel. You eyes move from the bottom of the  stairs to the top, and that's the first thing you notice. And also there is change in color, bottom of the stairs is dark and as you look up, it starts getting a little brighter.

This is a picture shows dominance because the burrito is the main focal point, it is the first thing you see before looking at the book and pencil next to it
