Overall, your topic is overused, but your dad is from Bolivia, making your situation a bit different. I think you should focus more on your father's background since it is what most makes your essay different. Another thing, I find how you phrase your sentences is a bit confusing. Try to reword your essay and make it as direct as possible with short sentences. I think you can make this a really good essay if only you put more effort on making it unique.. if you do not have a unique essay topic, you should focus on making the content special..
