I enhanced the image by adjusting the channel mixer to pop settings of 118% and -9%. I adjusted the curve as my next step to sharpen the image and finished it off with a dodge and burn to lighten the darker areas and darken the lighter areas. Overall I made the image more vivid using blend modes after adjusting the layers. The color of the leaves were on the duller side so I enhanced the green to show a little more detail. With the enhanced image there is more contrast between the lighter and darker areas of the flower without over saturation.
