My Blog updated look

I'm not an expert at HTML and CSS and at Google's Blogger templates but I've spent a few moment in the last few days to upgrade the look of my blog to make it a little bit less drab and easier to read. I hope you find it better too!

By the way, if there is a Blogger expert reading my blog, I'm still experiencing problem with the "Post" settings: I've selected different words that a user could click in order to leave his or her impressions like "interesting", "useless", etc. But those keywords don't show up at the bottom of each blog post as they should do. Don't know why. Help!
