Hello, thanks for sharing the photos...
Here's my little rundown on the images.
(just some comments... and I am no expert)
1. Sky looks a little over blown to me... a ND filter would've been a handy for this image. Other than that.. I like the scene.
2. THis one for me has a good sky. Only gripe is that the dark area at the fore ground is a little too overpowering.
3. This one 'almost' works for me... the poles on the bridge/pier get a little too blended into the background...
4. That's a nice summer scene ... I like it!
5. Favourite from the bunch... nice exposure and great with the rocks on the foreground. Good shot!
6. Would have maybe cropped this one so that the over blown highlights on the right hand side, behind the tree would be left out of the image. IMO this is better of your two shots of teh same scene (3 & 6 )
As I said, nice images ... and hope some of my comments you can agree with...
