Would you mind being more specific with regard to the feedback you're looking for? We generally frown on the "Hey, I just made a site, what do you think..." type of discussions (refer to #8 in the forum rules). The focus here is more to help people learn and improve their CSS/XHTML skills rather than just provide arbitrary opinions about websites.
Sorry, for beeing so unspecific. The main target should be to improve my css & xhtml skills to build well formed and w3c conform websites which are accessible to as many people as possible. An other important aspect is for sure the design and usability of the site. I really apreciate your professional look at my site and i hope that i can improve my skills with the help of all of you.
Err .. rules? 8. NO more "Site critique, site showcase, or site review". SkillShare's mission is to help with problems, and to discuss Web Standards and Web Design topics, NOT to review sites. If you need help with a certain problem on your site, then ask specifically about that issue.
Anyway, it's ok. Nice and clean. The un-aligned-ness of the navigation sort of bothers me though. Maybe a better font too. The site would look really hot with that sRIF anti-alias thing. :)
