First impression: Clean and easy to browse. (o_o)=b
The colours fit together, eventhough they make a dull expression to me. Since your site is mostly white, all text parts are a little bit hard to read, because of the pastel tones.

When I opened the site this text: Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'Gallery_Shortcode' does not have a method 'css' in /home/lukas/public_html/wp-includes/plugin.php on line 403 appeared first and it stayed the whole time while I was browsing. I guess this isn't supposed to happen or maybe it's just my browser (Firefox). I nearly quit the site because of this.

Your navigation bar is always visible, when I scroll down. Definitely a Plus but the same bar also appears above every single section your site content is devided into. One navigation bar is enough should be enough. (Since all of them work the same way)

To your skill chart: It's funny, but I agree with the comment of . You should shine with what your good at.

All in all, it's a very good site you put up. (^_^)=b
