People who complain about the hair thing know fuck-all about manga-derived styles. In case you haven't noticed, reality-sticklers, those huge honking eyes are the most important part of a character's expression. Unless you deliberately want to make the character seem mysterious, it's a GOOD idea to show as much of them as you can all the times. IT'S A CARTOON. CARTOONISTS FUDGE REALITY ALL THE TIME TO SUIT THEIR NEEDS. Next time you're gonna watch Tom & Jerry and complain that cats don't stretch that way.
