Having a peer review is very important when you are writing a paper of any kind. Having someone else look over your paper I a good idea because it puts fresh eyes on your paper. It also is a a way for someone else to look for any grammar mistakes that you may have made or if there is anything in your paper that might not make any sense. I find that sometimes when I'm writing a paper I like it to much and I can't find any bad things in it. But someone else who is open to the paper can give you positive feed back on what to fix or change.
