I don't know if this thread is still relevant
To be honest I believe nose is really easy compared to other facial features,
this video shows the form of the nose and how you can simplify it to get the right measures.Also even good artists suggest and use references when they draw something new or something they don't know really well.Finding references is easy google it or even look yourself in the mirror.

if you want help with the nose just watch this video


I like drawing portraits lately and I find practicing individual facial features from different people and how things change helps a lot with drawing them from imagination
