Let me start off by saying that a design refresh was necessary as well as that the new profile looks nice at the first glance.
On the other side I see multiple issues that have already been addressed in the other post: http://meta.wordpress.stackexchange.com/questions/4064/update-a-design-update-is-coming quite some time before.
The two major ones being:
- One of the big issues here at WPSE is to explain people that this is about https://wordpress.org/ and not https://wordpress.com/ which will be become even worse now that this design looks more like .com than .org.
- The design also looks way to similar to http://drupal.stackexchange.com/
Concerning the logo I'd like to just once more refer to what Tom said: http://meta.wordpress.stackexchange.com/a/4079/47733
To wrap things up I do not want to decry your work to refresh this communities design which was/is in fact needed. I just believe that it lacks in some pretty substantial ways and needs some more work.
