Hi Vikram and welcome to the Macro forum! The frog gave you a very nice pose and you captured it well with good sharpness throughout. There are few minor tweaks that would make this very strong image even better. You might clone some of the flash-generated specular highlights on the twig below the frog and some of the larger ones on the frog itself. The black background works well here and IMO it would be better if it was completely black - there are a few lighter blueish areas above the frog's back and also on the left side of the frame. These are not adding anything to the image and would be very simple to remove. Overall, this is very well done and I hope to see more of your work here in Macro!
