Tips for reviewing books?

I'm starting up a blog on wordpress.com to review books, and I was wondering if any of tu had any tips/things tu dislike about book reviews/categories ect.

I'm planning on reviewing the basics (author, title, genre, publication date, ect) as well as Cover Art, Characters, Plot, intended audience, my personal thoughts and recommending ratings (if i would/who I would recommend it to).

Do tu think I am missing anything?
