Just some photos 'n' stuff
Before I read your comment, mine was going to be, Goodness, that rust looks lovely when lit by the afternoon sun, but now that's just going to sound stale, and, well, copied! Drat.OK, let me say that those warm colours look simply gorgeous as they have been shot at such a golden time of the day! Well done. Loving the central and square composition too.
This really appeals to me because I think rust is always interesting but with the evening light, it comes alive. Great capture. Also, as Kim said, the circle tightly within a square is really works.
Lovely rusty color! eury
