Why should you examine your writing style with the idea of improving it? Do so as a mark of respect for your readers, whatever you're writing. If you scribble your thoughts any which way, your readers will surely feel that you care nothing about them. They will mark you down as an egomaniac or a chowderhead --- or, worse, they will stop reading you.
The most damning revelation you can make about yourself is that you do not know what is interesting and what is not. Don't you yourself like or dislike writers mainly for what they choose to show you or make you think about? Did you ever admire an emptyheaded writer for his or her mastery of the language? No.
So your own winning style must begin with ideas in your head.
