overall the theme is good, however you can do a number of things to improve it further.
1) Do we really need that big a header space. Perhaps you can trim it down a bit.
2) The navigation panel is kind of big as well. It is ok if you want to keep it that way, goes well with the design. However, speaking from the reader’s point of view, if the entire top un-scrolled screen is covered with such things then your content will get very few eyes.
the theme is good, you have done a decent job on it.
