It's a bit annoying how Google keeps finding the need to change aesthetics of YT every so often... plus, when you just get used to one of them, they roll right on to the next.
I find it's a bit "empty", and some of the little things that they have shifted around could have probably done without.
e.g. Moving the title of videos from the top (where you expect a title

), near descriptors, stats.
Searching for vids whilst viewing something can be a bit funny too, and their filters and recommended videos seem to be a bit annoying... or maybe that's just me.
