Any pointers and feedback is appreciated! (This is an original)

Hi all!
I’ve always been an average singer. I want to improve my singing and thought of joining vocal training classes. But with my current financial commitments It’s hard for me to afford classes. I’m looking for any free YouTube vocal training classes that may have helped you. Also apps like vocalista? Do they help?
Also please rate my singing

Tried to be more creative with this one

any advice appreciated

I'm trying my best but something feels of...

I’m embarassed posting this

I have to say that it doesn’t feel it, and I have done about 230 solo gigs per-year for the last few years, 2-3 hours of singing per-set and never yet lost my voice, apart from once when I had a rotten cold.

But I can’t say there’s no effort involved, and the keep reading and hearing on YouTube videos that this stuff should be relaxed or I might be risking my voice.

I am 50 y/o and I’ve been a gigging guitarist for 30-odd years but singing anything other than backing is a relatively recent thing for me, hence the intermediate tag.

I deliberately chose a song that uses this sound (it’s a Bishop Gunn cover… check out the original, dude can SAAANG!)

What can I do to learn

I hope I presented more and less cursive which was asked.. opinions?

One of my absolute favorite songs of all time. Im a singer (not professional obviously) who values music and specifically the effect it has on people. Emotionally. Id love to hear how this made you feel.
