Aaaawwww, what a cute sight to see - momma and her baby cub out in the fresh air! I think it is a good shot and average but it has potential to become a spectacular shot. As with any live models (be it animal or human) interest is always stronger if one can establish eye contact. If the baby leopard's face was looking more in our direction so we could see the darling eyes and face it would be all the more captivating. The protective momma looks down at her offspring but I can see a little of the fierce protectiveness in her eyes - but just a little more tilt to the head would show us more of her eyes and the protective stare. It is all in the timing and patience - sometimes you will get the shot and others not. If you have a rapid-fire or contineous fire feature on your camera this would have been a good opportunity to use it. Once you got the focus - then a quick click of the shutter at the moment you want would then take 4-5 quick shots one after the other. This would capture the movements and maybe one would capture the shot where eye contact is made. Of course with this feature it will then take a minute for the card to store and read it before you could take the next burst - so you have to choose the moment to click wisely. Now the colors - the reds and greens seems super saturated, some areas on the coat of the mother have a bit too much yellow tone in the spots. Keep the tones more to a natural look - if you want them to look a little more rich in Post-Processing play around with the Shadows/Highlights/Midtones or just contrast in the Brightness/Contrast levels but be careful here too for it is easy to go overboard in this direction as well. Playing around with the shadows and contrasts can also bring out some nice details as well - i.e. further showing more details in the direction of the hairs in the coat of the mother leopard.
Gorgeous animals. I wish that there were more separation between mother and cub. Their natural camouflage confuses my eyes like it is supposed to. But for a pic that is not quite perfect. :-)
