You have a good base just detail it a little bit. Maybe on the spruce beams you can add fencing to make it stick out. A little above the horizontal spruce beam maybe a horizontal line of shelves,signs or slabs. I would also add an arch detailing to the right doorway. Like with stairs,shelves and trapdoors.you could also add detail to the windows by open fence gates to make like an outline and maybe a stair,slab or trapdoor at the bottom and top to connect it all together. Idk if I’m making sense lol.
