It's good. Your voice is great, so I guess this won't help?
I listened to the link and to "All Talk and No Action" waiting for the flaws or the "greenness" in your voice, as you suggest.
There's no problem, so just carry on! I like your inflection which is interesting and colourful - you need that to entertain... and it adds a lot to your already-silky smooth tone, which is wonderful. Your body language is all right but you don't need to raise your shoulder. It might look as if you're straining when you're not. So perhaps it was a fluke and you don't do it again?
Finally, though it wasn't apparent, most can use some better breathing and relaxation in the presentation, which comes with more confidence, and it will help improve phrasing and cadence, also co-ordination with the music or accompaniment.
Like a bird on the wire,
like a drunk in a midnight choir
I have tried in my way to be free.
