You don't analyse the techniques - you analyse the choices the author has made in the way they wrote, structured, etc, the piece. If noticing a particular technique gives you a head-start on a good idea, great - but that's all they're good for.
For example: "Angrypancake balances the question of the second half of the sentence against a qualifier in the first half. This qualifier, stating what he/she
does understand is extraneous to the actual question, so is instead an attempt to persuade readers that he/she is deserving of the time they will take to answer because he/she has thought about the issue him/herself and has therefore 'earned' assistance. The opening word, "So", flags for the reader that the first statement is merely preliminary, building a level of suspense that arouses their curiosity about what is to follow. The active verb "struggling" in the second half of the sentence then creates an image of someone fighting against overwhelming odds, pushing against a mightier force and expending such effort that they may be overcome if not rendered assistance. The present continuous form of the verb - "struggling" instead of, for instance, 'I struggle' - enacts the moment of this battle and paints it as immediate and ongoing."
