I love the first (572, A Splash of Red) one, the colors really pop and I like the combination of the reds and greens. The moss-covererd tree is also a welcome element. I'm not yet sure but I think that my favorite is the last one 603, Beaver Pond, Mist). I like this low contrast. Initially I thought that it was a monochrome image but after a couple of seconds, colors were revealed. The third image (596, On the Docks) is more classical. I like the quietness and relaxing mood. I'm less thrilled by the second one (589, Autumn Morning)… There's some distortion on the trees (left side). I guess that you pointed your camera to the sky to get the nice clouds. Anyway, it's just nit-picking and would be easy to correct if you feel it needs to be fixed.
