I'm envious of your recent shots as this is not a very pretty time for us. We get little snow, the colorful leaves have fallen, and cold weather turns most everything a dull brown.
Creating "tension" in an image is a delicate balance of all the elements in the scene, it isn't easy. In your image my eye isn't going back and forth it's being dragged one way or the other and held. Yes light is an element of composition, but so is texture, color, and spatial relationships. The other thing about "tension" is you want interesting little features to catch the eye while wandering around, otherwise it will settle in the most dominant area. When you blow up the image there are some features on the hill, but at normal vewing resolution on a screen they aren't as obvious. Sometimes when we try to force an image in a scene that just isn't there, the intrest we envisioned in the mind before we snapped the shutter doesn't show up on the screen, IMO it's not on the same level as your other winter scenes.
