A great use of shaddows in this image. It creates an effective space for me without being a distraction from the main subject. It helps the photo rather than having a large plain blue space. A good idea.
Nice capture of the flower. The image is sharp, and the depth of field applied is quite good. I also like your colour choice for the border and words, as it matches the image very well, and creates a good, finished end product.
