mix
Wolf, you are getting there. You weren't in your mix register there, except maybe when you dropped into chest voice. Mix is just an easier way to sing in chest voice! Adding head takes the pressure of the chords.
Your head voice sounds pretty good, except you are still gripping your notes with your mind and your body. When you vocalize don't try to sound so good. Let it sound wierd and crazy. Don't hold onto the notes so hard. I myself micro-manage my body and that is holding me back.
