This is a lot more readable and approachable - nice work! Cool to see that the designers managed to stick to the green template while making it work for a bunch of different content types. Thanks for the update!
Yeah, there's a lot of whitespace - I'm not the biggest fan of all that padding on the blog / archive dates template, or the L-R padding on the home page, but I hear "more space" is all the rage :)
Mostly I noticed the difference in the Docs. The elements are called out more explicitly and it's easier to find things on the docs, which have considerably less whitespace:
