Did you bring the poor what exactly they want? Did you really sympathize and feeling their hurts? And whether you do these work with your heart? Those are what you should concern about.
this should not be included in such formal writing like IELTS. There are ways to use formal language rather than asking people's opinions
Plus, you should not use too many pronouns, especially : "You" which can affect your writing style.
Vietnamese do that without weighing the pros and the cons
"did" actually. However this sentence is unclear, it should be combined to the previous one.
These above are what i found in your essay. Hope these things will help you to progress your writing :)
