Painting/drawing noses - techniques?

[crackedskull]

Now the thing about drawing Mose- Ahem noses, is that its a 3d object and 3d objects are best brought forward in statues, try to wireframe(draw lines across a picture of a person indicating shape and form) a persons face and the nose.

Also for nose in small detail you should draw the bottom lines. Perhaps Dave's latest livestreams may be of use http://www.livestream.com/fuckinartwithmrdelicious
