You have a great composition here and a good subject but the shot is a little soft - or it was a small shot enlarged? Love the yellow foliage, but you will get hammered due to the quality element of the pic.
I like the contrast of colors, the blue sky the yellow of the tree. The detail in the shadows are also excellent. However I would have rated higher if the foreground tree were in better focus.
I expect that the full size photo is very good but that you lost a lot when you resized it. There as several things that could have been done to make the resized photo look better. The focus looks very soft in this photo, most likely this happened during resizing, try using USM after resizing to sharpen it up a bit. The photo also could have be resized to a larger size then this, using the full 640 will get you higher votes. The last point is try saving it at a high quality setting, this seems to be suffering from jpeg artifact due to too much compression.
oh, what a beautiful place. i hope you are not getting overlooked in this super-sized challenge, and that you are getting some good feedback. i like what you've attempted here, but think that your focus is letting you down. there are some things you can do in photoshop to actually bring out your background, and i would suggest that you continue working with this. as it is here, it is so-so, but with a little work, i think you'd have something that would look great on a wall. good luck with this, and the challenges yet to come!
This shot is kind of blurry, even the foreground tree, which I assume you meant to have in focus. The sky looks noisy and the background mountain is too dark. Sorry for the negative assessment.....
