Nice well done, you finally mentioned your focal length was begining to wonder what it was. Hope to get together one day and compare notes. Had a look at your webpage, some very good work. I like the quote on your home page "an art of observation" so many times when I was driving trucks I would be screaming to myself "LOOK AT THE LIGHT" and there would be no where or way to stop, even to use my phone camera. I rarely carried my DSLR in the truck.
I like your waterfalls, moving water is one chanllenge I enjoy and photographing the milky way in a scene is on my to do list, you've done it well. You can check out some of my work at the link in my sig if you're interested.
Then you get to crop/enhance/change colour etc at the touch of a keyboard.
It's not quite that simple. There are a lot of techniques that have transfered from film to digital just the execution has changed not the judgement on their effective use. I've seen some horrendously over processed images but it is always better to start with an image that needs little refinement.
