Norm, interesting post and I mostly agree with your assessment.
1) I love the type of sky this image captures, you captured it well. I think there is to much foreground and with a crop the image is perhaps good enough to print. ymmv
2) Unusual sky but this one doesn't really work for me and I can think of nothing to do with it. It sure is frustrating when I'm convinced that I need to over there to get the shot but it's impossible be over there.
3) I wonder how this would work as a monochrome?
4) My favorite in this group. This captures the north, I'm there and I am a northerner.
I do many lake shots and sometimes with near shore line I'm struggling with the horizon line. Straight is not straight and on some images there is an odd tension in the image that I find unsettling. I am generally pretty conscious of horizon line when shooting but still ending up crookeding some in post.
I hope this does not come across as pretentious I just hoping for some insightful comments and a chance to learn.
