Both this photo and Gathering Darkness 2 are good examples of photos with an obvious grain, where the grain adds to the image rather than detracts. Both have a old feeling, and this one in particular is more like an old movie than than an old photo- full of blurry motion.
I like the perspective on this one. And while it does feature a beautiful sky, I think the photo overall would work better with maybe a 1/4 less sky- but that's just my opinion, and I don't think it hurts it too much.
This one actually reminds me of a summer evening thunderstorm.
This was an extremely overcast day, and when I shot on black and white film I would often use different filters to help make the clouds more defined. Now you can do much of that in Photoshop, but this image was very much done "the old fashioned way." I think digital photography has come a long way, but there's still something unique and lovely about film.
