You are very welcome. One thing to keep in mind is that composition is not the only aspect of an image. I try to have images that will invoke some sort of emotion in my viewers, otherwise why take the picture, except maybe for documentation. Raising emotion in the viewer is really the hard part of photography, as it is not something that every photographer knows how to do, not do they understand how to achieve it - it is a developed/learned skill.
Part of this, I believe, is learning to previsualize your image. You see something - flower, butterfly, landscape, etc. and ask yourself "where is the 'story' here?" and if you think that there is one, then the next question is "how do I tell it with my photography?". As well, there is also the aspect of previsualization when you carry around an idea in your head about an image that you want to make and then watch for opportunities to make it. This usually means you have to figure out the "how" of making it as well. I always like to remember the quote from Ansel Adams - You don't take a photograph, you make it. I try to remember this when I am out there shooting with my camera.
