I really like what @thomastoth said about the inky feel, thats it exactly... super! The composition with these enormous shiny circles and melting checkered floor... all so excellent.
I love your subway photos - they always have a wonderful contrast in the light and dark. I've just ordered my Sony camera - the new ones have changed their name from Nex to A7 - very excited.
Love this pic. Nice circles and greatly timed capture. I like the action in her walking, the lifted foot. Beautiful line made by the wall, leading to the corner. Great play with contrasts, as ever! :)
I really like the urban feel of this shot. (My brain has no interrupted this comment to say- of course it's urban Ann, it's a subway!!) I like the graphic feel of the b/w- and especially the stainless steel in those round windows and the tile work around them. Excellent shot.
Those circles are very cool.
