I like the first shot and feel like you captured the environment and feeling very well. I also like the color tones and the added vignette, and disagree completely with anyone who says this photo "has nothing at all going for it", which seems to me more like bullying and not critiquing.
On the second one I'm not a fan of the intensity of the dark tones, but I do like the lighting on the surrounding mountains as well as the detail and color captured in the sky.
In the third shot I don't like the intensity of the bright spots; it makes it look almost as if the shot were taken with a toy camera or the lens was covered in vaseline. There's also a dust spot near the upper left corner that I personally would have removed in post processing. As far as being a shot that captures a memory for you though, I like it and see the value in it.
