I looked at your web site, and I can kinda see Framah's point. A lot of your shots look like you went out and shot some cool stuff, but didn't really have anything in particular in mind when you shot and post-processed them. For example, image 562 in your Wichita gallery. You have a pile of rocks, a live tree, and an arched dead tree, which are kind of all jumbled together. I'd have narrowed my focus to the dead tree, framed approximately 4:5 vertical, and hunted for a perspective to use the dead wood as a frame or border around one of the rocks behind it, preferably excluding the totally bland and featureless sky from the composition altogether. Overall, the image has a flat/bland look that really doesn't engage me, and the jumbled composition doesn't help.
8158OO35: You have a nice tree and a nice background, but you chopped part of the tree off on the right side of the frame, there's nothing of interest in the sky, and the look of the whole thing is kind of flat and bland color-wise. If I was shooting there, I'd shoot just a bit wider to give the tree some space all the way around it, and try to at least be there when there were some clouds or something the sky, if shooting at sunrise or sunset would be too cliched. Another thing I'd strongly consider (given the overall lack of interesting color in the image) is a B&W treatment. If color doesn't really add anything to the image, try removing it entirely and see if you can get anything interesting that way.
8159OO34: (the first image you attached in this thread?) Not bad compositionally, but this shot would benefit from more exposure to bring out more shadow detail; you're in no danger of clipping the highlights, so it wouldn't hurt anything. HDR blending would most likely be helpful here, as long as used in moderation. overall impression is dark and flat, not very enagaing or inviting.
1: Work on your composition. There's a difference between an interesting subject and an interesting image. Sometimes you can make interesting images from uninteresting subjects, and vice versa.
2: Lighting. A lot of your images have a flat look like you shot around noon on an overcast day. The flat look works harmoniously with an image sometimes, but more often it does not. If you find a good spot, don't be afraid to go back at different times of day and during different weather conditions to find a really good image.
3: Color. Many of your images have very flat, muted color. This is to be expected if shooting foggy/misty scenes, but in clear weather you could bump the saturation up a lot without being particularly unrealistic. Consider it.
Anyway, that's my honest opinion and constructive criticism of your work, worth exactly what you paid for it. Feel free to ignore it if you like.
