Apt title. Mottled body colours are very interesting as are those chrome coloured eyes! Great BKGD and perfect DOF keeps me focused on the head. Awesome shot.
Killer image and what works best is your composition the way the insect comes out of the left side of the frame and his head is peering right at the viewer from the center but with a cocked head. The colors work very well together and the head is sharp where it needs to be.
Very good Mantis portrait. They are difficult to frame well due to their long body and I like diagonal and cropping you did here. Was this in full sun?
