What's the context? Like have you been given a piece of work to analyse? I can give basic generic answers:
•The advertiser's want the audience to be engaged and interested in the advertisement
•The images appeal to the audience because it allows them to view the product instead of being described as to what it looks like. Also depending on the quality of the photograph it could allow and influence the audience's opinion on said product
•The setting/background of the background appeals to the audience as it can be used to divert the audience's eyes and influence what they look at. For example if the background is very bright and colourful and busy then their eyes will naturally gravitate there. However if the background is plain white or black then the eyes will gravitate to whatever is going on in the foreground. Many company's such as apple use this approach.
•Colour and font are used to draw interest to the advertisement and make it more memorable to the audience as bright colours and funky fonts will stick in someone's mind. This is why when making notes for things like exams people are encouraged to highlight and write in different colours as colours help the brain to remember something much more than opposed to black and white.
•Persuasive techniques that could've been used: -emotive language -direct address(using the word "you" e.g. YOU could buy this burger) -exaggeration -rhetorical questions -chatty style / speaking to the audience in a friendly way -anecdote(stories used to illustrate a point) -repetition -statistics(8 in 10 women would recommend)
I believe that the thrush's song changed the mood because it was a song filled with hope from the divine that inspired him. Darkling Thrush refers to a bird who is weak and fragile, however, even with these qualities, he sacrificed himself.
