Overall, the first shot is the best of the bunch, but it isn't perfect. IMO, I would have went with a higher f/stop to lengthen the DOF a bit. Just enough to have the whole base in focus and the rest not. All of the others are just .... not that interesting. I think the bridge shot (4) had potential but it isn't centered, the sky and rest of the picture is overexposed.
What could I have done differently in the bridge picture to bring the photo into a normal exposure? I struggled with what to do when I was there as the lighting was dull and there wasn't a lot of colour in the photo. Any thoughts or suggestions?
