Except for the fact that you were a little nervous, everything you said made perfect sense, good information. I just want to say that, for most beginners watching this video. extending your "speaking range" or just taking that speaking voice higher, will take a long time, don't rush, focus on strenthening that ligter coordination, make it as poweful and AS RELIABLE as possible, bring it as low as you can before increasing the ammoun of TA or even attempt belting. This is specially crucial for lighter voices.
