Answer:
The questions you need to ask yourself for the criteria are:
1. Above all, do you think this paper is worth reading? Does it apply to real life or what the author wants it to apply to?
2. Does it have well structured sentences? Does it make sense without you having to read it over again? Chances are if the paper doesn't make sense to you, it won't to readers.
3. Is there a point being argued? If so, make sure the author's points have validity and are true.
4. Peer review is all about opinion, so do you think in your opinion, bluntly, <em>is this actually good ?</em>
