Gorgeous transitions, so smooth and how you introduce the text in the header on each page is just unreal. Amazing job! I also really love the fact you've added a custom page scrolling bar, it's one of those little details that works so well.
If you wanted to go further and add another little detail similar to this, you could change your highlighted text colour to the gold used throughout the site. Find out how to do it here http://forum.webflow.com/t/change-highlighted-text-color/9843
I think it would add another bit of elegance and work really well. One last thing, I think the menu sliding in transition is nice, but the introduction of the 'close' icon could be sped up a bit.
All in all just a top class site, it shows how smooth, simple and consistent transitions can make a site look seriously slick. Congrats!
