Step 1, don’t waste 1/3 of my screen on a useless bar: http://i.imgur.com/4f41VPf.png
The bar is sort of important—it gets you to the blog index, as well as the service.
That said, I agree that it’s too large in the example you show. That’s the tricky part with responsive: so many devices to consider. (On most this size works quite alright.)
I’ve attended a few conferences, at which they offered “speed dating”-like sessions, in which a handful of UX folks would give quick feedback on sites. Most times, the attendees seemed to find this useful—even though the sessions were short.
So, we’re trying the same thing on Officehours. I spent the past few days reaching out to folks with varied experience, asking if they’d take part. We managed to get a pretty wide range of people involved, who I feel bring some unique viewpoints.
The sessions are free. There’s no trick or ulterior motive with any of this. It’s just a few people who don’t mind lending a hand. If you have a chance to take a session, please do. And let me know how it works out for you. I’m interested to see if this format has legs.
