Complex Blue Desaturated

This is one of the most complex flowers I have ever seen. I saw this at Lows the other day and bought it just to take pictures of! I decided to use this picture which shows the main flower in all it's glory. I thought I would eliminate the background more thank just Bokeh but by painting out all the color except the main flower. I liked the results as I didn't want anything to take away from the single flower's detail!
