Agree with everything here. One of the first things I noticed is the colors. I read about them using black and white to let users focus more on photos only to find out there are colors (blue/green) in links, follow buttons, icons in profile.
One more thing, when you love a picture, the heart icon is filled up in red color, although directly below it, the heart icon to show total likes is in black. Hmm..
All small details, but they all add up. Still a good redesign though, in my opinion.
