Hi Joshi. What an interesting looking eye and you nailed the sharpness within your narrow DOF! I think your image would be even stronger if you could have shot at a lower angle - at the Gecko's eye level instead of looking down at the eye. (Maybe that wasn't possible in this instance?) You might also consider some noise reduction on the background to smooth it out more. Overall, this is nicely done.
Hi Joshi, reptile eyes make for great macro subjects so I like this one! I agree that a lower angle might have looked better but I'm guessing that since you were using the built in flash, a straight on view would have reflected the flash right back at the camera. Sharpness looks good. Steve's suggestion of using NR makes sense. Maybe next time you can get a helper to light the subject from the side with a bright flashlight so you do not have to use flash.
Thanks All For Comments.. Steve, Ken, I also Have Low Angle Shots.. I will post.
In this pose, I especially Love Pop Up Eye, In lower Angle pose We cant see like this..
