Hello exiles, can i get some suggestions on how improve my build from gurus?

The build is a Storm Brand elementalist, nothing too fancy, I have already cleared a ton of the endgame content but Im looking for a way to further improve it.

Here is the pob: https://pastebin.com/qfhVkLT6

I don't know how to indicate pob that I have the arcane surge buff so I added an additional link

Any help/suggestion will be appreciated.
