What settings and lens did you use? I do like the idea behind the image, just wish you had used a wider aperture to lose more of the background, that pram really distracts me and draws my eye away from the main subjects. If a wider aperture wasn't a possibility then perhaps you could have gone for a tighter crop.
Love the B&W which supports the idea of the 'bleakness' of the image....but (and this is just my personal opinion) you've massively over-processed the image, making it look unnatural...softer tones would have been really nice here.
