Not seeing what the competition was that the judges compared this with it's kind of hard to say, but personally this shot really just doesn't grab me at all. Beyond any issues over lighting and contrast, it's just not an interesting composition in my opinion. To be more specific (which obviously the judge wasn't), to me this shot looks like something a person might use to analyze or evaluate a piece of machinery. The thought that comes to my mind is someone taking a picture of this "whatever it is" as a before reference to some kind of restoration or something. Photographically speaking though there's not a real sense of "composition". The eye tends to float around the image looking for a subject or an anchor point and there isn't one. In my mind at least, when I see a theme such as "junk, tools and machinery" the composition should reflect that, but it still should be a composition/well composed image.
While I could be quite wrong here at the risk of sounding blunt the impression I get from this shot is that you were given the assignment/theme and just looked around for something that fit the theme. Somehow this thing caught your attention and you took a "snap shot" of it thinking it would fit the bill without much thought about what it was you were shooting or any attempt to arrange or compose the image. To me, the word "composition" indicates a specific criteria that sets "snap shots" apart from "good photography" and/or art. It means arranging the elements of the image, either while shooting or later in post processing, in a way that's not only aesthetically pleasing but also follows some rough general concepts such as "the rule of thirds", lines, form, texture, juxtaposition, etc.. In most cases, a good composition goes beyond the subject matter itself...but without the subject matter, the rest becomes completely irrelevant.
Think of it this way...let's take a portrait of a child for example. There's LOTS of pictures of kids on this website alone to use as reference. Now when you're considering what's "good" about a given image, there are certain technical elements such as lighting, contrast, saturation and sharpness that certainly all come into play. But these things alone are NOT enough to make a truly great and memorable image (no matter what some "pros" seem to think). More often than not, it's the pose of the child that makes or breaks the shot. In other words, the exposure, lighting, sharpness, etc., etc., can all be spot on perfect, but if the kid doesn't have an interesting expression or something no one is going to look at the picture for very long. However -if- the kid has a simply great expression, some of these other aspects don't matter quite as much...and often can be fixed in post anyways. The technical aspects are still important, but they are not the end all, be all of great images. I think that's the big problem with your image here...it's simply not an interesting subject and just looks like a snap shot of some "junk".
A lot of folks seem to get hung up on the technical side of photography and don't put enough "focus" (no pun intended) on the artistic side. There are many folks that seem to think that an image that's sharp and well exposed is a "good" image. I know I've seen posts here on POTN where people will sacrifice virtually everything else in the shot just to have their lens in "the sweet spot" so that they have the sharpest image possible and will ONLY shoot at ISO 100 so their shots don't have any "grain", etc....but if the subject matter itself doesn't hold the viewers attention then all that other stuff really doesn't matter. In the words of Ansel Adams, "There's nothing worse than a sharp image of a fuzzy concept". Good photography is...or should be...a mix or balance of the technical and the aesthetic. It's a combination of -all- elements, not just the technical. Your image here is "sharp" and the lighting and color are decent enough and there's lines and texture....and what else? Not much really. There's no statement here...no story...nothing thought proving. See my point?
The next time you are in a situation such as this, my suggestion would be to put more emphasis on aesthetics and more thought into composition. Next time think more about the image from a "viewers" stand point instead of that of the photographers..."Is this something interesting to look at?" and so on. If it's not all that interesting to begin with, then just move on to the next subject and don't try to force a good image out of it.
Ok...I hope that makes sense to you. Not trying to be rude or mean, just my honest opinion...I hope it helps!
Peace,
Jim
