Small suggestion: You already greatly improved the workflow of actually submitting the review. One thing still bothering me is that the link to the page is not a normal link. You probably wanted it to open it in its own tab and therefore made it a javascript-link? Perfect usecase for target=_blank, which would also work with a middle-mouseclick (currently it just opens the review-page again).
PS: Are you moderating the reviews by yourself? If you add votes and have a report-system, it could be interesting whether an algorithm could do that work for you, maybe combined with the data-corpus of the reviews already in the system.
