You state at the end that the paper is an opinion piece, but there is very little opinion in the writing. At times, it reads more like a summary of the article. Either an opinion piece or an article summary would be a fine piece of writing, but you as the writer need to make it clearer which it actually is.
I think you will be better served by elaborating on your opinion a little bit more and developing the paper by adding another source. My memory of the assignment I asked for papers to be 3-5 pages long, and that would not include the references page.
