The second picture reminds me of Apple OS X by a lot.
Yeah, the floating middle menu bar has been copied a lot. I'm not sure if the overall design started with OSX or KDE. KDE definitely had it a really long time ago. The super sized icons, though, is definitely all OSX.
Find it odd you have GNOME at the bottom. Again though, I haven't given them enough or really any time as of late, to have an opinion. GNOME at least was my favorite but they could have ruined it in recent years.
