You have a great voice man, always a pleasure to hear.
Maybe a little too light on this take though...
when i go for the fatter sound, i think low......and it seems to get me the sound i want.
I actually discovered this singing Tom Jones tunes lol
Try singing Delilah before a tune like this,and use it as a guide for placement.
I swear it helped me get a meatier sound on my highs.
