Mmh first of all: Don't be nervous. You did well. The Video is good, the sound got better (at the beginning the music overtuned the voice, but you got there in the end). It's really a good quality Video, so don't be nervous.
I do have to critique the build tho. It's nothing new and not very creative. Subterranean Assault, Dizzy, Execute - this has been the warden meta since a long time now. I'd love to see somebody trying to think out of the box. Break the 2-hander meta!
Sorry for the bad criticism, but as said it was a good Video and i didn't get bored watching it. Good content, especially the multi kill with the Dawnbreaker was impressive. Clips like that will definitely get people to try out your build!
For Future: Set a Keybind to Hide enemy names, as this can cause trouble with ESO's policies and try to hide the Kill Counter. People jump on everything they can to call you out.
