***** (Larger View)

With such a large stamen and pastel, you were able to isolate them from the petals with selective focus, that helps the viewer stay focused on them. The background while OOF to some extent, really would have benefited from a more bokeh effect. 

The over all composition seems a little out of balance being crunched to the left, as you have more then enough room to have all the petals included within the frame, yet you clipped both petals on the far left.  A little more space around the flower itself would have greatly helped.
