We already have a storage, furnace and room to keep are beds in. I genuinly have no idea what to put here. Any suggestions?

I'm making a starter base in the new dappled forest but can't decide on a block palette that goes well, particularly the walls. The vibe I'm going for is a cozy autumn cottage. Any ideas?

Why does my build look so empty

If shorter is better, i'm planning to add like a mouth from the holes.

How can i terraform more naturally, everytime i terraform it looks repetitive and super flat!!
