When you do not have lips, but you need to smile

Cool.
Also, it is a creative idea to have a real smile. 

If it wants to smile that badly, to communicate that it wants to be friendly, it wouldn't go to this much trouble to injure itself if it's end goal was to kill you. 

I mean, you could just rip all the flesh off, your skull is always smiling.

Reminds me a bit of my old Dreamcatcher pic. Great job!

amazingly creepy and horrific, but beautiful at the same time

Great art and impressed meaning! I love it!!!

Lovely smile(s)!

I guess that means it is happy I'm glad about that
