Nicely done, Satish. Very cool species, interesting pose, lovely BG, good sharpness. Non-bullseye composition works, but I would prefer if you had lowered the camera a bit so the dragon was higher in the frame without changing your plane of focus. Also, I think I am seeing some masking artifacts--most visible along upper side of perch below abdomen.
Very nice detail, especially in the wings. Good job keeping the subject in the depth of field. Consider removing the red blob in the right upper corner.
