The header doesn't do the rest of the site any justice.There's something missing. It might be motion, visual stimuli that represents change or any element that represents your site a bit better. The cup of coffee doesn't quite represent change. Although I understand the message that you're trying to convey, the cup as a stand alone item, wouldn't be associated with your site.
Content, arrangement, motion, images -> outstanding!
All that's missing is a unique logo and associated favicon.
Nicely done!
