You are doing some very nice things to create a feeling of depth in these intimate landscapes. This image has a lot of potential but is not quite as effective as your others because of the contrast. You saw the detail from flowers to background just fine. The camera did not. It is overemphasizing the difference and creating a very bright background at the right that dominates the image. A little time in the computer with something like Lightroom and its local controls will help you control the contrast and better reveal your composition.
Thanks for the feedback Rob, I think I know what you mean. Have really enjoyed the course, which has certainly made me think again of Landscape photography. Hope you do a follow-up at some time.
