Very striking...! And a good pun! Good luck, I'm guessing top ten for this! I give a 9 - sharpness is perfect, contrast is too. This might be me being fussy but the stick in the top left corner is annoying me!
Fantastic subject. I think more saturation would have improved my score ... make it organic rather than dead. Remember rule of thirds ... bring the skull down a bit in the frame ... just a little ... 1/3 from the right, 1/3 from the top.
