A fighter jet

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 floating island ecosystem: a chunk of earth suspended in air with waterfalls pouring off multiple edges, a small forest on top, exposed roots and rocks hanging underneath, and smaller floating rocks nearby connected by ancient chain bridges

A phoenix rising from flames: wings fully spread upward, tail feathers flowing down like fire, head raised to the sky, made of red, orange, and gold blocks with glowstone accents

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

A steam locomotive

A flying aircraft carrier with a flat deck on top, control tower, planes parked on deck, massive jet engines underneath keeping it aloft, and radar dishes

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
