The ear is a bit high, but I think the real problem is the nose/mouth.
Generally the mouth line is parallel to the eye line. Here the eyes tilt but the mouth is horizontal. But you could get away with it if you fix the nose.
A face at level 3/4 view the nose sticks out.
When a head tilts towards you in 3/4 view, the nose still sticks out, even if the chin is down a bit.
A straight vertical nose usually only shows up when the head tilts away from you, and the chin is down (standard model pose #14)
Compare the angle of the eyes to the angle of the nose. Try out the angles in a mirror.
Maybe something like this (quick edit):
Hope this helps,
