Daniel L. Guerra... I wonder what that guy is up to these days...

Agreed.

That one too, it would be kinda weird seeing other cartoon characters. including the anime and realistic ones in that style. It wouldn't look authentic if you apply that style to. say. Steven from Steven Universe, he would look fine, but for the anime characters like Goku... It's another story...

And the same can be said to the japanese video game franchises like Super Mario and Sonic the Hedgehog.

True.
