My immediate impression is that this lacks any kind of point of focus - both in the sense of real sharpness of subject, and in the sense of clarit of single subject. 'm not necessarily suggesting that that is an element that makes for 'good' photography, but I certainly am suggesting that it will harm your score here at dpc. There is however, a very strong and cery likeable sense of light, and I also like your approach to the challenge - though that also will probably see your score dropping; which is a shame.
This could be considered fishing, as it isn't definitely a bridge, but aside from that, the composition and subject is remarkable, and the diffusing is very tasteful..
This is neat, almost gets impressionistic towards the top. My only complaint is that there's not a clearsubject that jumps out at me, somewhere where there was a clump or line of even bigger stones, maybe, would make for a more interesting shot.
Nice interpretation of the theme. Given the amount of blown-out highlights, it might have been better to stop down the camera to darken the exposure and gain greater depth of field, and then adjust the levels in PS.
