I guess 'kiss the nose cartoon' could be about showing tenderness or a light-hearted action in a cartoon. It could be part of a story, or just a concept. Maybe it's used to create a warm and friendly atmosphere in the cartoon.
Well, first, sketch the basic outline of the eyes and nose. Then, play around with the expressions - maybe make one eye wink or give the nose a funny tilt. Use bold lines and bright colors to make it stand out.
Well, such a cartoon girl might have a small and rounded nose that adds to her innocent and sweet appearance. It can make her seem more approachable and lovable. Also, the button nose might enhance her overall cuteness factor and make her stand out among other characters.
