Anime blog: change of layout

I'm about to start changing the layout of the anime blog. It currently has too much pink, and the width of the post is kind of narrow. If posting an image as large as the one seen above, the side would be squished.

I'm aware of it for quite a while, but the Twitter and Facebook buttons at the side doesn't work properly, especially the latter.

Background image is to be removed, but I'm compensating it with images at the header, and ones in the posts.
