How old do I sound?

This is a video of mine for reference as to how I sound. I care a lot about my voice. Ever since I was 12, I started using a microphone, and I used to get made fun of. Since then, I've been like "FUCK! I gotta work on my voice."

Now that I've been through most of the trials of puberty, my voice is now pretty good IMO. However, I wanted your guys's opinions of my voice, and how old I sound. A lot of people call my voice sexy or deep, but yeah. Can always use some more opinions :P
