Glad you like the photos. However I usually don't associate concepts with my photos and like to response to scenes instinctively without thinking too much about composition. Thanks for your advice nevertheless.
Okay, I guess I could rephrase that. Try this experiment: respond instinctively and take a picture, and then move about 30–50% closer to the subject and take another picture. It is my guess that viewers (including yourself) will like the results noticeably more. (The pictures I linked are ones that I wouldn’t necessarily benefit from the closer crop, but most of the others on your site would, IMO.) If in the experiment you don’t like the results as well as your original instincts, then, of course, trust yourself.
(For what it’s worth, the vast vast majority of my own pictures suck; it’s only through culling and cropping, and lots of practice, and hundreds of hours spent staring at prints, and then more culling and cropping, that anyone ever ends up with anything presentable.)
A lot of people go to school for a very long time, and (or sometimes or) then go on to practice for a very, very, very long time to take really good pictures.
After years and years and years of practice, then those people can start to get to the point where they can just take a picture without "thinking too much about composition." But that's only because they've been practicing composition (and all the other parts of photography) for so long.
Amateur photographers who consistently think about applying even just a few of the basic rules of composition (rule of thirds, etc) often have photographs that turn out much nicer looking than amateur photographers who "let instinct take over."
