Painting Noses on Baby Portraits

I think the most important thing to remember when painting a nose is that it is just a projection and should have no hard edges.  You are relying purely on shadows and highlights.  The nostrils shouldn't be too prominent and hard - keep them soft and fairly flat across the top.  The end of the nose should be the lightest - light areas indicate projection, dark areas depth.  Round the nose off with a light purple/pink shadow mix.  Noses tend to be a little more pink, especially on babies, so I add a little Permanent Rose to the mix.
