dont think you linked DRUPAL enough!
seriously a client doesnt care that much about knowing more about drupal, in fact once they see the drupal site they will run away scared!
interlink to interesting components of YOUR site instead. your link colours are very obvious and the only thing I really saw was drupal, drupal, drupal...
think like a CLIENT not a web developer.
as for the site itself, its not too bad, but justified text is difficult to read, particularly when its a bit waffly. what the hell is going on with that footer, seriously that search bar just looks whack!
put the rss with the social media icons, it just looks odd sitting there all on its own.
make your slider a consistent height, its really distracting how it jumps.
your whole portfolio is a bit wobbly too,
knockengine.com is that your first?, man it looks awful! it'll lose you more work than it'll gain, I would only place pieces you are proud of in your portfolio. and a grid there wouldn't hurt either...is john the painters image larger because its a better piece or your quality control was off that day?
the white dropshadow in the header is very distracting, whilst the main content headers have none whatsoever and probably could do with a bit of a subtle touch...
is there a need for 10 namespaces for the xml?
also there is way to much scripts in the head, place at the bottom of the document.
and I take it that you didnt name these css files?
css_TsVRTbLFUpEZAfw-_bWPJu840QT523CPjUVJ5MRWfyk.css
wow what a name!
trim the fat there as well and put all css into the one file. maybe even call it style.css so you know what it is!
