Hey Ivan, Some of these, although correct, would never be used in real life. However, someone would understand you if you used any of these. I will try and make them sound a little more natural below and maybe give some more colloquial sentences with a similar meaning. 1) She was about to change her perspective because of his persuasion. - She nearly changed her mind due to his convincing. - She was about to change her mind/her perspective because of his persuasive arguments. (You will hear/see "change your mind" a lot in English along with "made/make up your mind" like "Have you made up or mind about where you want to eat?" "Well, at first I wanted Mexican, but now I've changed my mind again and want Chinese food." 2) She was firm in her belief that her niece couldn't have framed her. - She was absolutely convinced that her niece couldn't have framed her. The use of "firm in" here is quite good though and sounds like an educated sentence. Also the word "resolute" is similar and you may want to learn it. 3) He swept the audience with a quick glance/look hoping to find his parents out there. - He quickly looked out over the audience hoping to spot his parents. In written English you will sometimes come upon the word group "swept his gaze across". You wouldn't likely ever say that, but it looks nice on paper. 4) He was shocked when they told him what that they required. 5) She was bewildered as to why he felt such loathing toward her. 6) He was rubbing the car with abrupt movements using a sponge so I asked him to take it easy or he could ruin the paint. Also with cars you will normally use the term "paint job" Like, "my car just got a new paint job." This seems to mostly be used with vehicles for some reason, although it would sound okay for a house too. A more common phrase of concern is "scratch the paint" vs "ruin the paint". Like if someone leans against your car you could say "Hey, be careful! You'll scratch the paint!"
