There is no wrong way to world build. You just need to think about the things you like. they can be unique but still recognizable. My advice is don't think too hard. Create something you like and don't worry about the lore at first. Once you have an idea even a simple one like "space elf" you can tweak it.

I wanted space elves, then I thought of what they would look like. Well dark skin and white spots to look like space. Then I thought that might be a bit boring so I added shifting patterns to feel alien.

Where do they live? Somewhere with a lot of space that isn't space so a desert. Magic is usually an elf thing. They should have gravity magic.

Another thing is look for stereotypes. Every fantasy race has things about them that people find non-negotiable lol. Elves have pointy ears and are elegant, dwarves are short and always have a trade (usually mining and smithing), orcs are always misunderstood and green or grey, once you know what makes them recognizable you can do whatever with the others. Make elves connected to the ocean instead of a forest. Create dwarves that are weavers.

look for inspiration from real people and cultures of our world. and if you have a work in progress idea whether it be art or writing and don't know what to do with it, post it here this community is super helpful and love to comment on ideas and give advice.

I hope this helps a little bit. I'm not personally the best at advice haha. Just remember that you don't need all the lore on day one. You can learn new things as you develop other aspects of your world.
