Icon for desktop software application

I need an icon for a windows desktop software. The application is a comparison tool called Compare, it compares projects and shows differences. I'm attaching an icon that I would like this one to take the basic lines from, but not necessarily. I'm also attaching a screenshot of an icon from another comparison tool, which might be used as a starting point. No need for name "Compare" in icon or abbreviations. Need sizes 48x48, 32x32 and 16x16. Thank you!
