Hmmm... never heard the term modern antique before. Regardless, the border is way too big BUT I do like it. Maybe half the size of that would be much better. Cool shot.
Nice composition, lighting, capture of the patina of rust and weathering. But where's the modern component? If the bolt were pushed through a shiny new eyelet, that might make the connection?
Modern Antique is a great Oxymoron. My problem is, I don't see anything 'modern' in the photo. Did you intend for the photo itself to be the 'modern' half?
