Not only does this shot have nothing to do with being a macro.. (you've made everything *smaller* in your shot than it is in reality), but the subject matter is confusing, the lighting is harsh, your white balance is off (too much yellow), the crop is too tight at the top, and too loose on the left, and the border is unnecessary and distracting, all, of course, in my opinion. Keep trying, but in my view, this shot is about as off-challenge as one can get.
You know, I think this is a fantastic photo from just about any aspect. And although I know that the challenge topics are subject to interpretation, it is a pretty far stretch to consider this one a macro, IMHO. I like the color, the compsotion, the hidden meanings that can be taken away from this....I just don't like it as a "macro". That being said, I'm still going to give this a score that is above the average for what I usually give but not a top score.
There'll be serveral people telling you that this isnt quite a macro, so let me say something different. The electrical socket looks somewhat out-of-place in an otherwise good collection. There is some reflection on the image immediately to the left of the switch.
