i dont think it can look a lot more realer than it does already
i mean damn, its too bad thats not pastry
you could make some cash off it
i live not too far from bongo javas (a few years back they had a some kinda something pastry that looked like it had an image of mother teresa on it, was all over the news, they put in a glass case and milked it to bring a religious crowd)
irl you can see more detail along the jaw, mandible, teeth, and nose area that is pretty crazy. every little detail looks like a little face of some sort.
but on your other note ive always wanted to make a metal plate for those little countertop waffle-iron/sandwich presses that you could manipulate to make virgin mary grilled cheeses at will.
