Rusty

 Rusty

I think this is a very good picture, because you cant define the object. You just see the rusty surface. Furthermore the front Part is in focus and has a very good contrast because of that the whole pictures very detailed and clear. On the one hand mystery and you have to think about it what it could be on the other hand it is pretty simple, but still very interesting, because of the many diagonals. All in all I think it is a very good picture.
