I like to throw in quotations, and parenthesis a lot.  I like to use little side statements, that add that voice.   Like this, "All of those underground caverns and hidden passageways underneath a city really capture how, once again using the term, radical..."  These show that I like to make things very obvious in my writing.  Also I love using a little sarcasm, this only works for me with quotations though.

I use some pretty short sentences just to show that they are really easy to see if you read the book.  I only make long senences when I want to explain something that I think is more dificult to see to the reader.  This is an example of a short and sweet sentence, "She has joined the Dauntless."
