I've had a few lands as a space player, it's kind of a but more challenging since one of the slots is filled with Frogs. I've had one which is Land of Spires and Frogs, sort of cathedral styled towers and flying buttresses extremely tall, which plays into both my aesthetics and my fear of tall buildings. Also having to find the Genesis Frog in frog chapels that the consorts live in like cloisters. The Denizen would live in an inverted tower inside a cavern with spires like stalactites.
Please have Echidna coiled around the main upside-down spire, that would be lovely. And yeah, Space Players have it easier to come up with their Quest, but harder to come up with a Land proper.
