Standing out for me is the left hand navigation bar, the new cover/profile image, the trending on Google+ section and the massive white space...
To add your cover photo, edit your profile and click change image. You can use a photo you already have uploaded (Google+ will alow you to reshape it in the right dimensions) or a bespoke one created by yourself: the cover photo size is 940 x 180 pixels. Don't forget that your profile image will go over the top towards the right so leave space!
Trending on Google+
As well as having the ability to hashtag things, Google+ has now got a similar feature to Twitter trends...in fact almost identical. Trending on Google+ shows you what is being talked about the most at any given time, in very the same way as Twitter. Found in the new Explore tab and on the homepage, extra features include a ranking indicator to show if something is on the up in the trending stakes or calming down and the option to 'join the discussion' around the trend immediately.

The option to have a specific URL for a Google+ profile or brand page is still missing; we are left with a mass of numbers at the end of each profile URL. In addition, although there are apparently 170m users on Google+, it is still too quiet for me to get really involved with. Google is clearly going up against the social media giants of the world and seem to be trying to create a network where your Twitter and Facebook needs can be found in one place. The jury is still out as to whether Google+ will succeed in its mission but the social media world moves so fast, anything could happen.
