I've been working on an iron farm in a survival world. I'm on 1.12 Prerelease 5.

It seems to work in 1.12, because Mumbo Jumbo built the same design on the Hermitcraft server.
It hasn't spawned any iron golems yet, and I have some doubts because this is the first iron farm I've built. I've looked over the wiki, and I want to make sure that I placed the doors correctly. Some of my friends are saying that there need to be transparent blocks above the doors.
So, all in all, I just want confirmation that I'm building the doors correctly. Thanks for all your help!
