Hey thanks for taking the time to listen and write this up! Appreciate the kind words as well. Good timing, just sat down at the computer to work on some music. I will definitely check out Robert Lunte. I am not training with anyone, no. That's cool to hear I could be in the lower realm of head voice. I can take my head voice really high but not with any control or without straining. Here's an example. I get to G5 but it's obvious to me my diaphragmatic support is weak hence the shaky transitions between passagios. After G4 or so, my voice is so inflexible that I can't really do anything with these notes at this point. Sorry for your ears lol.
