I hope this helps anyone else out who has trouble creating differently shaped eyes for their characters!
The rule of thumb is usually this: angular, and squinted eyes are for guys. Large round ones are reserved for girls. It can also display a type of personality, with the squinty eyes being reserved/mean/evil and the large ones outgoing/nice/good. Exceptions always apply, of course.
And here are several anime nose styles, I didn't work on various shapes, just a thin/regular nose.
