Ambivalence - I know Palermo reasonably well - had one of the best meals of my life there a couple of years ago with a number of friends.
what I most like about this shot is the kissing couple in the far left of frame - though they're so far toward the edge of frame that they'r almost excluded, which is a compositional critique in itself. there are other strong elements here - the two figures in front of the sign, the lights above and below the stall which parallel each other nicely...
However the faults far outweigh the good points: the blurring of the still pars of the image, the poor colour rendition (surely set to the wrong colour temperature, and nothing gained by it), the more or less pointlessly included area to the right of frame, the blacness at the top of frame ...
None of which are neessarily un-uselful elements, but there isn't enough of interest going on in hte rest of the picture to make them effective elements. It has an effect of being a first attempt at night photography, and the impression of being entered out of excitememnt at capturing a small portion of the impression of lights in darkness - but really there is nothing more to it for me. Not an intersting photo...
I hope this has helped you see why (and of course, it's only my opinion - though the score suggests it's that of a number of others too), and I hope you won't be discouraged by the result: this is a valuable and effective learning place, and the voting results on one's forst entry can be disheartening - stick with it, there are elements here that make me think you could do well in future.
An interesting photo - it looks as though the camera moved during the slow exposure, though. Maybe use a tripod or something to brace it on such as a table or fencepost? Or just stubbornly take a lot of pictures (since I'm not sure if the area allowed you to set up any kind of bracing). The focus is really good - I would say I can read the signs, but I can only say they're clear enough that they could be read in this case. :)
The thing I find interesting about this choice of shots is that when one thinks of "A Night on the Town," one does not normally think of fresh fruit stands. I think including people in the scene is important because it does qualify this as being a way to spend a night out. I'm not sure I care for the composition as much as the theme though. There is a lot of blurring on the sides and in the lights that may or may not be intentional, but which I don't find appealing.
