The point is your entire argument was handily destroyed and now you're being deliberately oblivious. Two nostril holes is a valid way to depict a skull. End of story.
My argument wasn't that you can't depict a skull with nostrils.
The 2003 skull somewhat works because the nostrils are shaped like the hole in a real skull, but I still think it doesn't look as good as the 1995 skull.
if you can make it look good, then of course nostrils are valid. I'm not trying to tell anyone what they can and can't do.
I was just trying to explain why I think the current Blockland skull looks weird.
