The later I am already demonstrating, using as few words to get my points across as I can (which, for someone who likes to add 'pith' or excess to my writing, is rather difficult). This is try and keep a consistent pace within the writing and getting as much content into the words as possible.
An abstract, on the other hand, is a device used as a 'hook'; a way to outline an argument or discussion, essentially telling people why they should care about what I'm writing about.
For example.
"My work in the studio shows the links drawn between their personalities, and the shoes they wear, and how both of these factors perhaps affect one another."
