This website doesn't even fit the purpose for a portfolio the information is so spread out its ridiculous, the design itself is flawed. I know this because My website is the same format. I get about 200 clicks a day from search & from pay-per-click and people don't bother scrolling. If the first tid bit of information isn't interesting, how do you plan on making any kind of money. Which is exactly why I'm splitting my website into multiple pages and moving everything up. Honestly imo for as long as I have been marketing websites, the first thing the user sees shouldn't really be the about page. Especially when its a portfolio site. The first thing a user should see is 1, your designs. 2, your top clients 3, how they can contact you / pricing. Don't make users scroll.
As for the color scheme now, the way it goes from light and dark is pretty annoying on my eyes at least for me. I feel like the headers shouldn't be inset but rather be popping out. The website in general looks rather generic. After reviewing your other designs, I agree with Manova.
