You took advantage of a great opportunity but there is no clear subject... the women's poses are interesting on their own without the background, i.e. crop out the unnecessary elements
A very busy image, but I'm sure that was your intent, to present a scene that would confuse anyone, becoming bewildered and lost. All in all, this image fulfills its purpose, but I think there's some things where it could improve.
Firstly: the title is "Where to Shop Next?" yet the three subjects appear to be admiring the decorations and elavators. I'm not sure if this was available to you, but perhaps a location change would've been more suitable: I like the tiered effect very much, however no storefronts appear. Maybe increasing the frame more so that bright neon signs are presented everywhere one looks. That would help implement the effect of bewilderness I think you're going for. I know when I go to malls, I'm intimidated by all the different storefronts and signs that are literally everywhere (which is why I don't go to the mall much... heh)
Secondly: I covered this a little before, but the image doesn't quite match the title. The subjects don't really appear exhausted from storehopping, and there's no shops in the image. Also, the elevator complex appears to be holding all of their attention.
Thirdly: I know it was candid, so this probably was a factor out of your control, but the subjects aren't really fitting for this image, in my opinion. I think what would've been a better subject is a man, a plethora of shopping bags in both hands, looking exhausted, surveying the scene I mentioned earlier, an overwhelming display of neon signs and storefronts. I think personally that women are immune to the bewilderment I experience at malls. But that's a whole nother topic.
Forthly (and Lastly): Just a bit of technical stuff, but their feet are cut off and the railing seems a bit crooked. Also, they seem like thy're too far away and don't hold much presence to be the subject. I'm more drawn to the red and green present more in the middle. Perhaps taking it on the same level as the subject, as to provide a view of stoorfromts, complex decorations, and a subject with more holding power.
Hopefully that was helpful... I tried to keep it short ; )
