Nice chain!
But the ground looks like a cracker.

The shallowest but possibly most beneficial suggestion first. While the
lie of the chain is quite possible, there is usually a more random look
with the links collapsing on themselves more rather than "pulling"
against each other so consistently.
I can't settle on the scale involved here, and that affects the sense of
appropriate scale for the rusting.
I would expect more difference between the rusted areas and the worn
areas. In general I would expect fresh rust would have very little
highlight and would having a caked-on look different from tarnish.
I think the overall effect is excellent for giving a generalized sense
of rust, tarnish, and corrosion. But when you observe it to try and
identify the actual material and process involved, it starts to loose
some impact. Are we seeing, rust? Tarnish? Corrosion? Wear? Or some or
all of these in combination? I think if part of the color or finsh was
seen to vary with the changes in surface, that would probably help
enough. Or else, if we are to beleive that the surface was so
consistent in finish, maybe the rusted areas would be a little less
random, maybe be more related to the structure of the links themselves
or occur on just one side?

I think you need to work on the texture. The rust looks smooth and shiny.
You could make it rougher by adding a variation in the normal on a small
scale (maybe with the wrinkles or granite pattern but not scaled too big).
Maybe tighten the specular highlights. It might also help if you make it
look like small bits of the metal are "peeling" off; look at the small
hole-like things in http://www.eleganthack.com/archives/rust.jpg to see what
I mean. Sharp changes in the value of the normal pattern combined with
abrupt changes in pigment color can do that. These are just ideas, keep
tweaking it.
What is the chain for? What is the surface it's lying on and why is it
there? Right now I see an object, but if you answer these questions it might
look more like a "scene."

Rust. Definitely. Too shiny. Imo, it should also stick out of the metal a
tiny bit, lying on it, as it were, instead of making integral part of the
metal.

Even assuming you were going for a "forged iron" look for the links (as
I guess from the color and finish), a chain wouldn't be that rough. Cut
back on the normal; you want slight imperfections, not faux leather. I
wouldn't expect an iron chain to be that dark, either.. but I know some
iron IS that dark, so I leave it to your judgement.
As for the rust... Usually, when bare iron rusts from exposure to
moisture in the air, it doesn't go in bits and pieces, it rusts all at
once. If you can find photographs of a rusty chain or something similar,
you'll probably see that it all just goes kinda dull and brownish.
The spotty kind of rust you have here is usually the result of
corrosion.. either the iron has some kind of exterior coating or finish
that wears off, or it's been splattered with water drops and then left
alone. If you want that kind of rust, you'll want a more corroded look
for the rusty areas.. pitted, chunky, fuzzy, and/or flaky. You'll also
want a really dull finish and some color variance.

I think it's the scale here that's the problem with the main image.
Something doesn't seem right with it to me. I dunno, try and match the scale
in that reference image somehow and see how it looks then?
I don't have a problem with the rust though, close (to me), but needs
'something', I don't know what.
