Service Icon Stretched out?

Hello,

On my site http://www.noboundsmarketing.com my service icon got stretched out when I implemented a child theme on Sydney. When I use the parent theme though they are not stretched and are perfectly circular? I don’t have any CSS coding..I was playing around with the coding yesterday and something made it stretch but I’m having a hard time locating what it was since it’s not showing in the parent theme and only under my child theme…when my child theme has no custom CSS applied!

Thanks!
