Have seen one of your other videos and enjoyed that one as well. Nice easy feeling and "homey" touch. Slight blip in the sax playing (why didn't you redo this?). If vocalist was a sax player there would be a recommendation to practice "long tones". Her voice is basically good (in tune, good feeling and inflection, etc.), but tends to go into a nervous waver instead of vibrato some times. Nailing tonal quality/control on long held notes is most important for singers and sax players as both can wreck what is otherwise a good sound/tune by losing control. Not much work needed to make this top pro quality. Whatever you do don't lose your easygoing feel as it connects really well.
