Sandra, I also say go for it! You are one fantastic guitarist and now you are also a very good singer. As suggested you could go to a vocal instructor to take you over the top, not that it is all that far for you! That is the route I would go if I have a voice like yours. The other option is to use pitch correction, as noted your were a little pitchy, but be it far from someone like me with no vocal chords what so ever to criticize. Personally with a voice like yours I would take Mac’s advice and get a good vocal instructor.

I also agree with Jazzmandan as I didn’t hear a foreign, at least foreign to me , accent!

Ps, now I’m even a bigger fan of yours!
