I love when people contribute by making reviews here on vizzed.  If I may make a suggestion or two though.  If you expand on each section as to why you gave your scores it would be more fun to read.  Also through in some personal touches about your experience with the game and it will make for a really good read.  Though I do respect your straight to the point review.

As fightor put it, you should definitely aim to make the review a little more personal and descriptive. By expanding on each category and highlighting on the good or bad aspects of the game according to you, the reader can get a better idea of not only the game itself, but also what it offers and if it is worthwhile. There isn't anything wrong with getting straight to the point, and you can still do that even by adding some of your own personal experience with the game. 

Your review should aim to answer any questions the reader may have, and either persuade/dissuade someone to play a game. You can do this by thinking about common questions like: why are the graphics good? How do they compare to other games in the series, or games of the same console? How do they add to the game as a whole?

You can easily make your review more detailed by anticipating and answering what the reader wants to know. I hope you find this commentary to be useful rather than harmful. It isn't my intent to discourage you from writing reviews, rather, I am offering this advice to help you improve. I hope to see more reviews from you in the future!
