Thanks again for the comments. The third shot is seeming to be a crowd favourite when people see it. The branches just have so much to say the way they are gnarled and reaching out across the photo. As soon as I saw the tree, I knew I had to photograph it.
Even if you dont use an action, I believe you could get a similar effect on #3 by duplicating the layer, then applying a gaussian blur to the dup layer. Then with the blurred layer on top, set blending to overlay or soft light. The amount of gaussian blur will depend on the size of the image, probably 14-20 for a full res image, and maybe 4 for a 700 px wide web image.
