Thank you all for insightful comments!!!
Ramesh, I agree the noise grains are bit distracting, probably the major portion of the image is in mid tone range, noise is more prominent. Lesson learnt
Dheera, Nirlep, I wanted an anchor point in the image, hence focused slightly on the anther. I have another image where anther and filaments are OOF, somehow the whole image was looking too soft to my taste.
Its a great learning experience in CNP!!!
