I reckon your singer has a good voice for more jazzy stuff, she can hold a tune and does move a little bit to try to entertain folks, so full marks for trying, but on first listening it seems like the entire set has been transposed to suit the singer's range, which in this instance doesn't really work for me. Also you as a bass player and your guitarist could try to move a bit more; if punters just wanted to listen to music then they'd be drinking kestrel super strength in their front gardens on discarded sofas, punters need to be entertained, and it's everyone's responsibility to ensure that that happens.
I know it sounds like I'm being really picky, but I've had similar problems in the past with shoe-gazing musicians who were excellent players but not entertainers. That's a real bug-bear of mine, as if only one of you makes the effort to move around a bit you risk looking like that drummer at the wrong gig (you've probably seen it on here before now...).
Bottom line is to find some songs that your singer can do in the original key, or find a singer who is more versatile. Oh, and move a bit more, even if you have to consciously choreograph everything at first, it'll make a difference in the long run.
