Pretty cool. I did tractor chains too, but I think yours are better. Specifically in the interest department. Good yucky, dirty feeling going on in this photo.
a good idea, 'though i agree with the tighter crop, more texture stuff. or, crisper focus, possibly iwth a high pass layer, and a high contrast presentation.
I'm sorry but I have to agree with previous post about tighter cropping, maybe on the middle chain showing more detail as sort of an abstract? just a thought. As an ex-John Deere mechanic I like the shot though, I have seen plenty of these, lol.
