Wow! What a sighting Praveen!

The eye contact is nice. It is always a pleasure watching an animal with cubs. And when the subject is a leopard, it goes over the top.

It is good that you used f8. The depth of field is good. I agree with Dipankar that a vertical would also be nice. Slight tweaking of the colour temperature (bringing it down) will further strengthen the image.

Did you get any images of the mother licking the cub? Only one cub? Look forward to more from this series.
