first, congrats on the site, it looks amazing!

There are several tools that allow you to diagnose why a site is slow, for instance:

In this case, there is an image that's way too large (almost 8 MB):

hope this helps!

We also had an issue with this theme being incredibly slow on another build (Core 8.1.0 Long Story Short 1.1.2). We had 5 slides on the home page. The content would load quickly but the javascript took over a minute to finish loading so the parallax and menu wouldn't work. We isolated javascript code until we found the cause for this particular site. In the main.js file there is a Modernizr test which seemed to be slowing everything down:

if ( typeof Modernizr.inlinesvg == "undefined" ) {
            Modernizr.addTest('inlinesvg', function() {
               var ns = {'svg': ''};
               var div = document.createElement('div');
               div.innerHTML = '<svg></svg>';
               return (div.firstChild && div.firstChild.namespaceURI) == ns.svg;

This appeared to be pointing to a deprected url
We changed this to and now the page loads in 2 seconds.
