Wicked awesome you're finally getting on T! Congratulations! In certain parts of your video, especially early on in it, I can see/hear that you're struggling to hit some of the lower notes in the song- it looks a little forced. When you get into it and start singing in a range that is more comfortable on your vocal chords, it shows, and you sound great. Applause for making a video to document your voice pre-T, especially with talking. Even if you aren't interested in putting one online(for obvious reasons) you may want to do an experiment with recording how HIGH you can go/how fluidly you can manipulate a higher pitch pre-T(You may have done this already, I haven't watched any of your other videos). I'd be interested in doing that personally as well, in the future, because while your voice will obviously change, and you'll probably be able to hit more deeply with increased ease, difficulty with higher ranges could also strike as well.
I've been interested lately in how our voices often differ recorded from how we hear ourselves when we talk; this has made me interested in posting a video of my own! Anyway, you have a nice singing voice. Since you're obviously taking care of it/practicing with it pre-T, you'll probably sound beautiful once your voice stabilizes on T, as well! Looking forward to future documentation, bra.
