Hi from Brazil

Hi, my name is Tiago and I live in Brazil. I've been singing for about 2 years now, but only this year I abandoned erudite singing and bought Ken's course. I was classified as a bass by every vocal teacher I ever had, so I struggle a lot with high notes. The course has been great though, in only 3 months or so I went from a F4 to a G#4(but I can't really use it for songs).
Anyway, yesterday I sung in front of a crowd for the first time in my life and it went great. Far from perfect but that was expected. I'm gonna leave the links to our performances below and I'm open for criticism.
