Solid plan and I have a feeling that elemental foods are going to play a big part in production and really ramping up the quality of your lands being worked and is a logical first place to expand. Buildings are going to be important but I feel like that's going to be the long game 10 levels , all costing time and grain while not producing and then constant wood and stone. Just remember certain land types allow certain construction for wood and grain come land 2.0. Good luck out there!
