I think it's an excellent site overall. The areas that stick out to me are:
- The pictures are a bit too big IMO. I love pics and I personally have them for all of my own articles but I think in your case they eat up too much real estate. For instance, even at a high res on my laptop, I can only see 1.5 lines of content since everything else falls beneath the fold.
- The header/nav is elegant but there's also a lot of white space. I understand that the logo (love it, BTW) is portrait so that is forcing the height but perhaps you could lower the nav and add a banner above it? The banner could be your own, like a link to a coupon or white paper.
