A very nice picture, nice rendering of the structure on the cicadas back.
Impressive DOF, have you used a tripod, or is the cicada that big 
I used a color profile in LR (iPad) thats made this structure more visible, its usually grey to the human eye
No time to set up a tripod so it’s hand held
In the absence of VR I used iso 800, f4, 1/250sec
The cicada was 5cm in length
I took several photos and try to have the eye in focus, I used flash with better overall lighting just once before cicadas fly away but no lack in eye focus

Thank you
