I guess my question would be is there any reason why you chose to go black and white on these?
Mostly due to color, or lack there of.. With the exception of the stop sign, the originals were nearly monochromatic to begin with. Not much color to be found these days at this latitude.. I thought that, despite the lack of color, these still had plenty of good tonal range to make good B&W's. Is there something about the edits that's not jiving with you?
Well, my own aesthetic tastes probably differ from a lot of folks, but in all honesty? Not a huge fan of B&W photography. I find it for the most part overused and frankly generally pretentious. I've seen a few B&W shots that work - mostly portraits in which the B&W added a certain dramatic flare or on rare occasions a landscape or non-human subject in which the primary subject matter is old enough that it was around when B&W photography is all that was available. An old barn or steam engine, for example.
If it were me I would probably try to use the lack of color in the color shots to my advantage - place something colorful in the shot for contrast, perhaps an old scarf, an apple, an autumn leaf from a tree if you have one close enough by - something.
Odds are good I'm likely in the minority here - lord knows I see enough B&W out there to choke a horse - but I guess that's why it really doesn't do much for me personally. It's just been done to death.
Again, one man's humble opinion. Take it for what it's worth.
