Delete smiley face and blank space from the bottom of the web

Hi,

I created this blog:
and your plugin is causing a little bit mess at the bottom of my page.

Do you know what is the smiley face that appears at the bottom at my blog, at the left side? (under the footer menu)

Why is there an space? (between the footer menu and the limit of the browser?, how can I eliminate it?

Thank you

P.S. I still think however that your plugin is awesome! I don’t want to quit it.
