I envy your deep voice... Enjoyed the song, liked the chord progression... and I thought your harmonica playing sounded quite good in the mix! I'd have to agree that the vocals are a little hard to understand.
I always enjoy your songs.. you have a real down-to-earth style that resonates with me.
You can train a dog to jump through a hoop by positive reinforcement. But if you kick him just once after he jumps through the hoop, he will probably avoid the hoop from then on. The same principle is true of song writing.
