Feels like Grow has a similar concept in creating random worlds, except there is more of a sense of wonder and even fae than Nightingale's Realms.
Again recommending random Realms be smaller, maybe featuring one or two major landmarks so that it'll take several Realms before the player has seen "everything" (i.e., every type of landmark).
Also landmarks can be in different configurations, such as sometimes just one statue, other times a whole bunch of statues perhaps in an intriguing pattern.
Re-use assets in different ways and possibly add interesting scripts to some of them. This lets you have more landmarks without as much work trying to make completely new ones.
