New: Did I choose the right build?

I just started playing PoE a few days ago after finding time to sink into a game while I am on Paternity leave for the next month. So far, I've tried following a build that I found online but I'm not sure if it's a durable build. Looking for tips and direction on what to search for next, or what items I should replace.

Build I'm following (with some not-quite-there-yet modifications):
