sorry late on this: like the lyrics, like the casio...the singing....maybe ...well...if randy newman and bob dylan had a baby, and it was raised in the woods, and had never heard music...yeah.
and, i'm really, honestly not saying that to offend.
i'm thinking that if you'd like to improve the voice...maybe a bit of blues and gospel might not be a way in...think early van morrison...you need to rip into it a bit more, just too reticent. there are parts where you kinda get passionate, and the voice looses it's waver, and stays on key...other than that, it's all sort of weak and emotionally ineffectual.
hope you don't mind the intrusion.
lift up your head...and remember what your life is !
