I think the site is pretty good, but there are a couple of issues I think you need to consider.
1st, the size of what is essentially a header block (The coffee cup) is way too big. What this block does in each page, is essentially nothing different from a header, and yet it takes up almost the entire above the fold area. As for the coffee cup image itself, while it's not horrible, it does beg the question: what are you selling? Does a coffee cup somehow universally denote "great web design?"
2nd, you use strong lines to separate your sections, and it's well known that this subliminally indicates that the content is separate and complete. This is again going to discourage users from scrolling to see your content. You could probably come up with a way of breaking that seperation as you did at the top with the breakout corners on each side of the Header.
