HiHi Peter, The feel of this mechanical mastrodont is very well captured; beautiful in it's ugliness, and it creates a very intriguing and strong scene. Good lighting and a well balanced compostion;
I do feel a bit ambiguous about the toning, but that's more because I generally speaking don't see the need for toning a photo, as most of the time it induces an uncalled for atmosphere. In this case, I think that applies too, but as I haven't seen the original, that's always difficult and subjective to judge.
I believe it distracts a bit from the worn-down structure, obscuring the textures and materials. Besides, it reduces the separation between foreground / primary subject and background. This is not necessarily a bad thing, though.
