What a great composition. I have not seen one quite like it before, and I have seen way too many flowers! The colors are rich and creamy, and the background is appropriately blurry. Now for the critique that would take this image to the front ranks of nature photography - OR - abstract photography. The depth of field is too shallow. The flow edges need to ALL be sharp, and not all edges are sharp. Secondly, I would crop in on both sides to help eliminate the extraneous green (and clone out ALL the green on the left that remains). Also, even up the crop to make the top of the image the same distance from the flower as the bottom edge.
