Sounds like you are on your way man. I would say just keep working on your tone, as you seem to know your range and you fit the country style well.
However, your intonation is still a little out. That can be helped by simply singing scales, singing along with melodies on an instrument; the methods are endless to help with that. Staying in tune is key. :)
I found a lot of help through using the CD that came with this book. I don't think I have ever even opened the book, but the CD I have completely worn out. Give it a try, and thanks for posting this. Very brave indeed!
