A nice photo!
And I would perhaps agree that the technique is better
But it doesn't have the drama or quite the sence of a moment captured that the others do ...
I know what you are saying when you talk about understanding the kit and improving your photography through a greater understanding of how to manipulate the and the software ... These things are obviously vitally important for getting better at photography...
But image content, ie the direction you point the camera and when is probably more important ...
Those first shots might have blown out highlights and might not be taken in the golden hour ... But they do capture fleeting moments where beams of sun have shone through cracks in clouds and created dramatic interest and the sence of a moment captured!
I'm perhaps not re right person to talk to about landscape photography though, I don't like what has become the standard in the world of landscape pictures! Perfect exposure, slightly over saturated colours etc you see so much of it these days that all looks te same! It's almost as if there is a set of instructions that people follow ... I compliance to a set of rules - golden hour, use of nd grads, no lost high lights etc etc
As I said, I agree that learning the techniques is a good idea, but don't set them as rules for your self! After all they really are just other peoples rules ... You follow other people's rules and you loose the sense of self expression ...
A good photo to quote another member here, is one where the technique is invisible! What shines through is the content ...
