Very interesing neon sign. To my eyes, you might have done more with this in post processing to really make it stand out. The building reflection in the background has a lot of noise in it which is kind of distracting. I think, if you played with levels you could get the background to be darker and the sign to be brighter and really pop out at you.
A very interesting composition, the distorted reflected buildings especiall, are eye catching. The neon, which is the point of the picture, is kind of dull (for neon) against such a well-lighted background.
Very grainy and, perhaps oversharpened. I think this would have looked better if you used a polarizer to cut the reflections and give the cactus a floating appearance.
I would suggest cropping out the area of black at the top as it introduces a jarring angle which distracts the eye with no payoff. Unfortunately, you've also seemed to capture your own reflection (or that of something else) which is a bit distracting. The lighting seems a bit drab, almost like daylight, and doesn't enhance the shot. This kind of looks like one shot superimposed on another. The neon sign and the reflection of the windows don't harmonize well. I'm finding that the neon intrudes on an interesting study of the window reflections.
