How to make this look human This is my second try to model a character this time I set the goal , that the model looks similar to me.

I have put really much effort in this, but I'm not happy with the result. It doens't look human.

What is the cause? How can I better imitate a human? How can I make it look like me? Which parts of the face should I rework? Is the texturing right?
It's not too bad. I couldn't say about the texture because your picture is too dark. But about the proportions I would say:


Lengthen the forehead
Shorten the chin
Scale down and spread the ears
Scale down and rise the nose up
Scale up the mouth and thicken the lower lip
Make the neck straight
...


To compare you could overlay your photo with your mesh, either in Blender or Photoshop.
