I was pretty surprised when watching because you have a really similar tone to a Korean singer named Rose from the girl group Blackpink. I'd recommend watching her videos because I personally have learned the most watching people with similar voices to me.

I think if I was you and planning on singing in public soon, I'd stick to a song that stays in a more comfortable note range and avoid the high notes near the end of the video. They were pretty good but even in your body language, you seem to tense up trying to get the notes out. Singing in public can be scary which might make it more difficult when the time comes.

But you should definitely take lessons! Or maybe even learn a specific song to get better feedback :)
