New Textures?

Hi guys,
I'm new here and I just recently downloaded the game with the newest textures from legion and stuff. So I would like to know how do I use them? How do I apply them. Because right now I'm really confused after loggin into the game having the same old textures. Was it even worth to spend so much time downloading it all? (my internet suck) Thanks for quick answers.

you do not need to do anything.

Skin texture should look better and you have access to some new hair style. That is it.

Btw, because of WoD/Legion models:
1. You have more chance to crash while in Dalaran
2. you can't use gnome mount while in a big city
3. In some case your enemy in Arena will be invisible for you
4. Game Crash if you try to spectate an Arena Game via the custom "spectator npc" (I am not sure if this bug has been fixed)

Well, they don't. Nothing happend everything look the same old way. I'm confused little bit.

Well, nevermind I just restarted it and its done. Anyway thanks for answer and these tips appreciate that.
