the blacks and whites look a little flat to me and the object in the background is distracting. Don't really like that white vignette on their either especially on the bottom left portion of the photo.
hmmm personally I like it. I think Mike is right about the hardware on the back there. If you're going with the vintage look I think the vignette looks nice, it's the gadget on the back and her clothes that somewhat contradict the theme though.
