Interesting abstract theme for your header. Even though that blue ball is quite big, blog title is noticeable, but you should make the subtitle shorter, it's rather long now.
I like the navigation, it's clean, simple, efficient.
Articles have really dark background and are hard to read. You should either make the background lighter and text darker or opposite. This way, my eyes got tired after only several minutes spent on your blog.
Make transition between your articles and page footer more noticeable. Right now it's hard to tell when does an article end and footer begins.
I am only able to review the design of your blog because I don't speak the language it was written in.
