                                   How to draw a nose and a lip on a side view

How to construct: You always want to remember, the front of the top lip always goes forward of the bottom lip, so I just added the centre the lip  that overlap the bottom lip a little.  The bottom lip again, is a little   bit fuller and a bit more circular in shape. The top lip looks a little more triangular from the side. The top lip needs to be shaded in darker then the bottom lip. Always remember to draw the middle part of both lips to get a better result.
