Write at least two complete commentary/analysis sentences that explain...
--how the imagery supports the advertisement's rhetorical strategy
--why the imagery is important to the ad
--what the imagery suggests about the product being sold or the people that use that product
Commentary sentences are the heart of your argument, so think hard and take your time.
Also, watch your commas, periods, and capitalization, please.
Example: The vanishing crowd imagery works on two levels. First, the image of suddenly empty streets suggests the lovers' intense focus on each other -- no else exists in the world--and therefore pulls the audience into their story. We understand how they are feeling and sympathize with them. Second, the imagery implies that the iPhone 7's camera helps create and express that kind of passionate romance. On both levels, the imagery supports the appeal to pathos running through the whole ad.
You may use "we" and "our" as you write. Avoid "I" and "you."
