I think that the combination “clouds + wind” is extremely interesting for landscape photography, since it causes continuously changing combinations of lights and shadows. In such cases, I usually search for an interesting subject and then stay for some time, shooting every few seconds. The next two images have been taken with an 11 seconds interval.

Both shots are good in my opinion, conveying different feelings, even though I have a preference for the latter.

Remember also to change focal length, as while you are concentrating on a single subject, interesting things could happen around it. For instance, I like a lot this third shot, where two trees are taken with slightly different lights.
