I've been looking at Pyke's model...

The attention to detail is pretty amazing compared to older champions. Like in his laugh animation, he actually takes off his mask and it shows that he has a face underneath there, with a fully moving mouth and everything. And it's not something that you'd regularly see unless you really looked. I know, a lot of the newer champions have those little bits too, but it really just warms my heart to see that Riot is putting so much more effort into character rigging.
