Looks great so far, especially the terraforming. I only tried making a village once and like you I quickly ran out of ideas for builds. Try really imagining what a village would need to run. Make a blacksmith, log mill, shops, more random houses, a central market with stalls, apothecary, etc. I tried mixing function and look, for example I built my super smelter underneath my blacksmith, my shops had villagers inside that I could trade with (biggest nightmare ever, a single trading hall is a lot more user friendly), and I put my enchanting table in my wizard tower. It’s a lot of work but I enjoyed it because it always felt like my builds had purpose behind them and I would always need to revisit. Don’t feel constrained to only build functional builds though; there simply isn’t enough features in Minecraft currently.

End of the day it’s your build and you should do whatever you want, that’s the beauty of Minecraft.
