Make Email Button Bigger?

I love this plugin, it looks better and loads faster than some other ones and is easy to customize the way I like.

I do have one question though… Sharing by email is a pretty important part of the pages I have the vertical bar on since they are usual an image attachment page.

Anyway, I was wondering if there is a way to make the email button more prevalent. I know it runs through sharethis but I was hoping there was a way to do this, maybe with CSS?

Thanks and keep up the great work on this plugin!
