Change Header/Section Title

Hi, I’m new to WP. Everything mostly makes sense. I’m using a free version of Elegant Theme 2.2.0. It’s great so far but I really need to be able to change the title of a section of the home page. You can view my site here: I need to change the “Recent Works” title to read something like “View our portfolio”. I see the values for that header in the css but I can’t find where the phrase “recent works” is referenced in any of the editor files. This is where my knowledge of how WP works is low … maybe I’m asking a stupid question. Maybe I need a more customizable theme but I really like this one.
