Colin......you're putting out some good stuff, so....my comment would be to "take some singing lessons."

But.......don't get your knickers in a twist until you read on.

You have an excellent voice....extremely soothing. I really like listening to your tunes. So......since you already have an "excellent voice" to work with, I would take that asset and improve on it even more. Learn to breathe properly and that will then help you to.......

STYLIZE A SONG: simply put.....hold on to some notes longer than others by using breath support.

And...interpretation.....focus on interpretation...very important.

Donny did a great job of "interpretation" on his version of Let Me Try Again (Frank Sinatra). I have it here if you want to listen to it.

Not sure if you're looking to improve or just want to belt out some songs here and there, but if it's the former, then consider the "singing lessons." Not everyone is given a good voice to work with like YOU have!
