What do you think of my singing again?

I honestly hate to break your pipe dream, but your singing is mediocre, if not worse. With practice you may improve, but I don't see any way you can p tryouts to get into any musical conservatory. If you love doing, by all means continue, but do not expect people who are serious about music to ever tell you that you have 'talent', or whatever it may be. Apologies once again, and have a great day!
