It has come to my notice about how different some nose trills are. If you are Caucasian then you would probably be used to the elongated shape, and if you are Asian – Mongoloid race then it will be the circular type that you are used to.
I managed to get two comparison pictures in my lecture today:

left – my nose, right – my lecture’s nose
Not such great quality pictures but they are enough to show the difference. Mind you that they are taken in two different angles that actually make my lecturer’s nose trills looked less elongated.
