I like the ideas behind what you've created - but a bit of constructive criticism from my part;
OnePage designs are becoming more and more of a popular choice for companies out there, I get it, having a single page display information that everyone needs, rather than having to go through pages to find information, its just one long page. The idea behind it is great, but I think it's becoming too common of a website to really WOW someone.
To me, I'm looking at the items in your portfolio and your website itself, I feel like they're all the same. I mean, they look different, but they have the exact same functionality and design as all of your work has, and not just you, but everyone out there at the moment is doing the exact same thing - I think being unique is important. While you're great at what you do, my piece of advice is to do it, but add your own ideas and creativity to it, show people why they should hire you, and not the other guy they were looking at before they got to your website.
Also, i will have to agree with Soundwave, the navbar when it's not fixed at the top is rather big, and bulky, I'd make that smaller.
