Hey Rayna
Sarah's absolutely right, your natural vocal tone is uniquely yours to keep and you should treasure it!
Voices change over time, and you will naturally sound more mature with practice. Correct technique and practice will support your natural tone and allow you to sing using your given voice with confidence and control.
I have a naturally high voice and range. Personally, I've found that singing with an emphasis on chest voice / resonance makes me sound more operatic, like Pavarotti, which sounds more powerful and authorise when you belt out with confidence
