I was having a look at your site, I liked the layout, so was looking at the source as I was curious as to how you put the site together when I noticed you had made two calls to google fonts for Lato:500. If you look at the fonts available for Lato on the fonts.google.com site you will notice that lato:500 is not an option resulting in this error:
https://fonts.googleapis.com/css?family=Lato:500, Failed to load resource:
Again, I liked the site and the layout, great work. This note was just in case you missed the error.
