I have a nice editor review that I recieved in regards to a load of writing I did for a site that I no longer write for. Is it appropriate to include that review in a portfolio? If so, would it be best to paraphrase or simply paste in the review, stating where it came from?

I don't have the one good writing reference that I know will pop out at potential clients, so I am looking for anything to spice up the portfolio a bit. Any advice on this is greatly appreciated. Thanks!
