The subject here is very interesting, however I feel that a more interesting angle could have produced a better photo. The image here seems a little flat, with no depth to it. The tracks could have produced some interesting elements in this.........the crop is a little too close as well to make this work
I think you have a very worthy subject, but the angle chosen has flattened the "tractor" so it has no dimension. It also looks like there might have been a hard direct flash which has also flattened the image.
Seriously rusted. Looks almost like suburban houses behind it; if possible I'd shoot from even farther down if it would get them out of the shot. Light is quite harsh (like from an undiffused flash).
