I spent three evenings on the nose alone for a portrait and it still looks wrong from across the room. Up close it's fine, the values are there, the highlight is where it should be. Step back and suddenly it's a mouth. I don't understand how my eye can be so careful for six hours and then betray me at the one distance that matters.

I think my problem is I keep drawing what I know a nose is instead of what the light is actually doing on this particular face. I get attached to the idea of it. Has anyone else hit this, where a feature is technically correct but it just doesn't sit right in the whole? Do you fight it by redoing the whole passage or do you walk away and come back with fresh eyes? I'm tempted to leave this one overnight and see if I even still recognise it in the morning.
