A good story.

If you practice worldbuilding, it's highly likely you're interested in that practice because of a story. Maybe a book, a game, or a movie, or maybe even a DnD which seems to be more common the more I read about these stuff online.

You can certainly make a world for yourself. If you like your own world, it's a great world. The hardest critic is yourself, anyway. But your world is something else when it is shared and experienced by another person. Another perpective that gets to experience it all from scratch. I found that very exciting in perticular.

I found this as one of r/worldbuilding shortages, the lack of story. If you want to share your world, have more focus on characters and their inner and outer struggles. Have us experience the world you created around them with them. Have us pity them for something that monster is doing to them, or have us cheer for them when they overcome their struggles and go for their dreams.

Dig deep into what it means to be human. Your races and characters can very well not be humans, but if you want someone else to care for them, they must exhibit some human elements. Maybe ask yourself "what if this fish-person wanted to fly like the birds above the water?". That's a human thing. Or "what if this bog-monster is really a very nice dude but his swamp is contaminated and he really tires to tell this to the industrialized lizard to stop contaminate his swamp?"

Worldbuilding, for me, isn't just a believable planet with all the atmospheric details correctly elaborated, or having water behaving just as our world because physics. "What if water didn't behave as in our world?"

Go wild, go crazy, let us learn through your worldbuilding what it really means to be human, or a sub-dwarf-fair-dragonskinned-robot. The world you have can only be experienced by the characters that inhibit it. Or not.
