We are largely ignoring noses. :o People can get away with drawing just a suggestion of them in stylized drawings (heck just look at the characters at the top of this page) but they used to be considered difficult.

Oh, and this isn't an advice thread per se but I wanted to mention, if you're learning art, don't try to hide things you can't draw (or draw well). It's really transparent and you'll do better to tackle the issue. You know a lot of it is just practice.
