Make adjustments to form a 'nice' ear here the modeling technique relies on your anatomical knowledge, also I advise you to stare at peoples ears around you :)


Grid in subdivision 2.

Fill the hole which remains with quads and triangles.




Insert the series of edges (high left).

Select the two vertexes and weld them to remove the triangle

Finally select the external edges like opposite.


Extrude these edges in the direction of the head and made a uniform scale to make the round-off of the ear.



Select the polygon all at the bottom of the hollow of the ear and make one Extrude and Bevel to make the hole of the auditory canal. On right-hand side seen in subdivision 2 with cage LPM.



How the ear looks with subdivision 2 before assembly.
Put a material with highish specular so you may see the contours of the ear well for any further corrections.
The ear must be stylized enough and yet have regular curves.
