Judges it in a careful and thoughtful way.

Explanation:

An author's style is the way an author uses or employs his words to signify or present his work. This literary technique greatly adds meaning to the work, be it the choice of words, the figurative language used or the sentence structure, etc.

And when a reader is to evaluate any given work of an author, the evaluation will be done solely based on a careful judging and thoughtful way. He/ she will focus on the tiny details, the overall structure of the text along with the word choices, and small fragments of the whole text. This entails judging the work/ text in a careful and thoughtful manner.
