All 3 shots are well exposed however I will make the follow comments:
Shot 1. I think you have too much sky in your photo and the picture is split in two with the horizon. Crop half the sky off and your picture gains drama and impact.
Shot 2. This is a well exposed photo but it lacks any drama. I would consider cropping out half the foreground and you will gain with just one point of interest ( the highlight on the horizon)
Shot 3. Well exposed and good composition. However the cloud formation is rather dull and fails to add any impact to your photo. This is of course beyond your control and on another day it could be so different. Perhaps another visit.
The first is the pick, nice catch with the light refelcting off the wet rocks.
If your cropping the 1st, check your hoirzon.
The tower is a tricky customer and hard to get a good composition…. not helped with the proximity of the water tower. I have yet to take one that Im really happy with…. but thats half the fun :)
