principles of 2-d design

not being an art student this is my first real graphic design class but i have taken other art classes so I'm familiar with the importance of design in a piece of art. This chapter brought to mind concepts that might seem obvious but are sometimes overlooked-it is very easy to look at an image and decide you don't like the composition without knowing how to fix it. i think this chapter touched on basic ways to improve an image and things to consider when making a design.
