A cozy cottage

An astronaut

A fighter jet

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

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 classic arcade cabinet with a joystick and three buttons on the control panel, a screen showing simple graphics, coin slot on the front, and artwork on the sides

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 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.
