I don't know about you, but I've yet to see orcs or elves that are very close to what Skyrim did. They now seem like totally alien species, ones that would be subject to racism.
Orcs are tribal, primitive outcasts and worship an evil god; not very original. Most of the elven races are well-trampled; anything that might distinguish them from normal RPG tropes appears nowhere in the game. The human races are somewhat more interesting, at least.
Not to mention all the unique environments they've added, like Blackreach, the glacial north, etc.
Some of the environments are pretty well done, agreed. Not many complaints here.
Also, there is plenty of detail that is somewhat original and interesting, even if it's heavily themed from other stuff, the giants with Mammoths, the Forsworn..it's definitely a decently unique vision for a game, it just borrows heavily from traditional sources.
Giants and their mammoths, and the Forsworn (why do I think of Frank Herbert's
Dune whenever I think about them?) are definitely some of the, or maybe the, best aspects of the game. As for the rest?

Meh.
