I think still life studies are a great way to learn this concept before applying it to landscape work. With most still life subject matter, there's not very much depth to work with; most items are usually at a close viewing range. You have to really work at seeing the more important vs. less important areas.
Looking at this image of the finished piece, I'm feeling a little daring and am thinking of going back to it and doing something crazy with the background. There's a good chance I may end up destroying it (as I many times do when I get these crazy urges). But without the confines of the original scene in front of me, I can simply think in terms of making a dramatic piece of artwork with interesting composition, color combinations, etc. I've learned not to get too attached to any painting so that I can have fun getting a little crazy every once in awhile.
