Very clean and easy to navigate. Has all the elements of a solid website, however, the same situation that i pointed out still applies. While your "MARS" logo is animated, the rest of the icons on the left doesn't have any function. As a user, when i see that your site navigates with ease and intuition, then my logical assumption would be that the rest of the site is functional as well.
Also, your banner, just to cover the essentials, should link back to the frontpage as well.
Your reference section is great, you're leaving the conventional ways of displaying your work, looks very good.
Other than that, much like last time, your site is extremely professional, solid, navigated with ease, even for a person that doesn't speak your language. Which, if you want to conquer areas outside your country, after all you're on NP in English, you might want to consider an English translation of your site?
:tu: great site!
