Another tutorial of my own without tracing it. I've created the guiding of my own as well. But at the moment, I'm trying to work out how I could variety the noses around rather than just always circle it.
There are two tips on this tutorials. Hope it could help you somehow. Just let me know.
And of course, I should mention this... The noses are best to start with before you draw the eyes, lips and ears because noses are the centre of the entire face. Try that. It worked for me.
