This is a tough one to critique inasmuch as I'm not sure what I'm looking at. Maybe looks like some rusted steel implement of a sort deep in some brush. Nice capture of the rust colored whatever. I'd maybe consider backing up a smidge so that we could see the whole doodah. Not sure that the branch encroaching in the upper right adds much to the image.
I'd go with Dorothy on backing up a little bit from it but not too much... this is a curious shot actually, it's strange, it's like there's a contradiction with the almost perfect vertical lines shown by nature against the way the man-made object has just been left there so slap-hazardly, it seems the wrong way round, but that's just how it is! I like it when photographs give me something to think about, I have to go and mull over this now. Thanks for sharing and giving me a spark of inspiration! Gem
