Manga face

It's not actually a REAL manga face.. its just two eyes on a simple face lol to show you how it looks.. i don't have any idea for drawing a nose and mouth.. any suggestions?
I also think i improved my eye drawing

here is it:

For nose and mouths, here

You can keep it relatively simple and use two lines for the nose. (The nostrils)
Or just use one line across to represent the whole bottom part of the nose. (Septum + nostrils)
For mouths, A simple line will do, though most people tend to indicate the bottom lip
