As you can see, I replace my banner, add top links and add an RSS Feed sign on the side of my blog. Aside from that, to add more design in my blog, I created Review Headers so that my reviews won't look stale. Here are some samples.
For Anime/Toku Reviews.
For Manga Reviews.
I am planning to edit all my headers within next week. :) I will not create headers for my book reviews since it is hard to look for pictures that came exactly from the book... unless it is illustrated, I will make one.
