The only regret I have is that the foreground foliage isn't more interesting - maybe some colorful flowers? As you may have realized, one of the techniques I enjoy is shallow depth of field. It's not useful in all situations. But I like getting in close and using larger apertures. If you haven't seen it before, check-out some "bokeh" images on Google. This is a Japanese word for controlled blur or the aesthetic quality of blur or out-of-focus. This is can be accomplished quite well using a 50mm 1.4 lens with a large aperture setting with the camera close to the focus point. Here's one example (click on image for a better look):
