A skyscraper

A steampunk airship with a wooden hull, large brass propellers on each side, a balloon made of patchwork fabric above the deck, hanging ropes and ladders, and a glass-enclosed bridge at the front

A massive world tree: an enormous trunk with roots visible above ground forming archways, multiple levels of thick branches like platforms, glowing fruit hanging from smaller branches, and vines draping down

A medieval stone castle with curtain walls forming a square, four tall corner towers with battlements, a central keep, a gatehouse with an archway and portcullis, and a surrounding moat with a small drawbridge.

A cozy cottage

A steam locomotive

A treehouse village: three large treehouses in adjacent trees connected by rope bridges, each house with different architecture (one rustic, one elvish with curved lines, one modern with clean angles), rope ladders down, and lanterns hanging from branches

An underwater shipwreck: a wooden galleon on its side on the ocean floor, holes in the hull, coral and seaweed growing on it, treasure chests spilling gold, and fish swimming around
