Just a thought, but how is drawing them white ethnically neutral? It seems like something more beige/brown would be, seeing as how most of the world as tan-skinned.
I think it's largely because the page is white. How do you color someone beige/brown in a black-and-white medium? Specifically black and white, not grayscale.
A question to you: What is it that makes them drawn specifically white, other than eyes? Is it only the fact that they're on a white background, or is there more there that I am missing.
