2. Turn on Weight Type mode to check if the weights are evenly distributed across the jawline. (Most of the time the head is fully weighed to the head bone up to the point of contact with the neck, so this should not matter.) If they aren't, keep that in mind during the next step.
3. Either in that mode or after returning to normal with Wire+ enabled, correct the shape of the jawline if isn't to your liking by manually dragging symmetrically positioned/matching vertices on both sides of the model's face. You do it with orthographic projection enabled ([Switch Perspective] On/Off) and by adjusting the camera angle in side view until your reference elements (those that you know to be symmetrical) align. You can also use the Multi View mode (F12) instead, but I find it more cumbersome.
4. Make sure the weights are evenly distributed after correction if you did it.
5. Go to Light settings and try to replicate the lighting you see in the picture. You can also load a simple single-file shader that enhances the contrast between shadows and lit parts. (Very optional.)
6. Here's the neat part: select the vertices in the area where you don't like the shadows and go Edit -> Normal -> Average Normals (Face). You can also use other methods if you don't like the result. Normals can also be corrected manually from the Vertex tab of the editor.
7. For the love of all that is holy, make a better ear with at least some semblance of shape...

>>2832608Naturally, you don't even have a name? I think it's this though:
