Hi dai! It's great that you were able to create and publish your work so quickly. If you feel more comfortable keeping it unlisted, that's absolutely fine. The most important thing is that you're happy with your creation. If you ever decide to share it publicly in the future, you can always do so later on.
I made it in 5 seconds and published it, then it was embarrassed to be listed on the top page.
Let's publish it unlisted!
